Michael Faraday

Michael Faraday was born on 22 September 1791 and died in 25 August 1867. He was an English scientist who contributed to the fields of electromagnetism and electrochemistry. His main discoveries include those of electromagnetic induction, diamagnetism and electrolysis. Faraday’s family was not well off. He received only a basic formal education. When he was 14, he got a job in a bookstore, and spent all of his time reading books. In 1813, Faraday got the job of the chemical assistant at the Royal Institution. In 1831, Faraday discovered electromagnetic induction, the principle behind the electric transformer and generator. This discovery was crucial in allowing electricity to be transformed from a curiosity into a powerful new technology. During the remainder of the decade he worked on developing his ideas about electricity. He was partly responsible for coining many familiar words including 'electrode', 'cathode' and 'ion'. Faraday's scientific knowledge was harnessed for practical use through various official appointments, including scientific adviser to Trinity House (1836-1865) and Professor of Chemistry at the Royal Military Academy in Woolwich (1830-1851). However, in the early 1840s, Faraday's health began to deteriorate and he did less research. He died on 25 August 1867 at Hampton Court, where he had been given official lodgings in recognition of his contribution to science. He gave his name to the 'farad', originally describing a unit of electrical charge but later a unit of electrical capacitance.
The electric generator consists of a tube of neutral material wound with a coil of wire, insulated in cotton, and a bar magnet. Faraday connected his apparatus to a galvanometer (an instrument that detects electrical current) and discovered that when he passed…...

Kirtley Jr. September 5, 2005 1 Introduction Bearings Stator Stator Conductors Rotor Air Gap Rotor Conductors Shaft End Windings Figure 1: Form of Electric Machine This section of notes discusses some of the fundamental processes involved in electric machinery. In the section on energy conversion processes we examine the two major ways of estimating electromagnetic forces: those involving thermodynamic arguments (conservation of energy) and field methods (Maxwell’s Stress Tensor). But first it is appropriate to introduce the topic by describing a notional rotating electric machine. Electric machinery comes in many different types and a strikingly broad range of sizes, from those little machines that cause cell ’phones and pagers to vibrate (yes, those are rotating electric machines) to turbine generators with ratings upwards of a Gigawatt. Most of the machines with which we are familiar are rotating, but linear electric motors are widely used, from shuttle drives in weaving machines to equipment handling and amusement park rides. Currently under development are large linear induction machines to be used to launch aircraft. It is our purpose in this subject to develop an analytical basis for understanding how all of these different machines work. We start, however, with a picture of perhaps the most common of electric machines. 2 Electric Machine......

Diy Magnetic Generator

...Permanent Magnetic Generator Construction Manual http://HoJoMotor.com Our Team Doing an On-site Assembly in Peru http://HoJoMotor.com Section 1) Introduction This manual describes how to build a 'permanent magnet generator' (PMG). We can also call it an 'alternator', because it generates alternating current (AC). It will not generate 'mains voltage' or 'utility power' AC. It generates low voltage, 'three phase' AC, and then changes it into 'direct current' (DC) for charging a 12 volt battery. What this PMG is made of 1) EXPLODED PMG The PMG (see diagram 1) consists of: • • • • A steel spine and shaft. A stator containing coils of wire Two magnet rotors A rectifier The stator contains six coils of copper wire, cast in fiberglass resin. This stator casting is mounted onto the spine; it does not move. Wires from the coils take electricity to the rectifier, which changes the AC to DC for charging the battery. The rectifier is mounted on an aluminum 'heatsink' to keep it cool. http://HoJoMotor.com The magnet rotors are mounted on bearings, which turn on the shaft. The rear rotor is behind the stator, and enclosed within it. The front one is on the outside, fixed to the rear one by long studs which pass through a hole in the stator. The wind turbine rotor blades will be mounted on the same studs. They will turn the magnet rotors, and move the magnets past the coils. Magnetic flux passes from one rotor to the other through the stator. This moving magnetic......

Patterson Wind Generators

...(Patterson, 2014) In this small article that is up for discussion, I will be bringing foresight of understanding about Flying Wind Generators. In ways it is better than resourceful energy such as your free standing windmills or even such as standby generators. This is exactly what the name states a flying wind generator better known as BAT (buoyancy airborne turbine). Just think of all the places in the world that is struggling due to the prices or material needed to produce mass electric. Most of these places have the use of windmills which only pick up so much wind with the height that it stands at. Another resource of power is a standby generator, into which you are burning resources such as diesel or any other fossil fuels that are harmful to the environment. Do you believe there are better ways to generate power for numerous of housing or businesses. Of course there is and this BAT I shall give you my perception. According to CNN This dramatic idea its a dramatic idea that could change the course of countless of lives around the planet. This BAT which is 35 feet wide and can be folded up and stored for traveling in a container is lighter than any other electrical resource. It flies at an altitude of just about 1000 feet above ground which does not affect ......

...deflected from magnetic north when the electric current from the battery he was using switched on and off. This deflection convinced him that magnetic fields radiate from all sides of wire carrying an electric current, just as light and heat do, and that it confirmed a direct relationship between electricity and magnetism. He published his findings, proving that an electric current produces a magnetic field as it flows through a wire. The CGS unit of magnetic induction is named in honor of his contributions to the field of electromagnetism. The magnetic field encircles this straight piece of current- carrying wire, the magnetic flux lines having no definite “north” or “south” poles. While the magnetic field surrounding a current- carrying wire is indeed interesting, it is quiet weak for common amounts of current, able to deflect a compass needle and not much more. To create a stronger magnetic field force (and consequently, more field flux) with the same amount of electric current, we can wrap the wire into a coil shape, where the circling magnetic fields around the wire will join to create a larger field with a definitemagnetic (north and south) polarity; the amount of magnetic field force generated by a coiled wire is proportional to the current through the wire multiplied by the number of “turns” or “wraps” of wire in the coil. This field force is called magneto motive force (mmf), and is very much analogous to electromotive force (E) in an electric......

The Electric Revolution

...Wijeratne MBA/15/3904 08th October, 2015 1. Introduction – The Inception of the Modern Electric Vehicle The concept of the Electric Vehicle, although generally conceived as a modern invention, finds its origins as early on as the turn of the Eighteenth century. An electric vehicle (EV), also known as an electric drive vehicle, uses one or more electric motors or traction motors for propulsion. An electric vehicle may be powered through a collector system by electricity from off-vehicle sources, or may be self-contained with a battery or generator to convert fuel to electricity, the latter being the base for the modern electric automobile that used globally today. Electric Vehicles first came into popular existence in the mid-19th century, when electricity was among the preferred methods for motor vehicle propulsion, providing a level of comfort and ease of operation that could not be achieved by the gasoline cars of the time. Contrary to the trends in most other sectors, greenhouse gas emissions of the transport sector are still increasing, and are predicted to grow further in the coming years, at current policies. As there is no simple solution to the challenge of achieving significant CO2 reductions in transport, it has become clear that a large range of efficient and effective CO2 reduction measures will have to be taken. In the coming decades, it is clearly evident that electric vehicles could play a significant role in this move towards sustainable......

...pollution in many California cities is accelerating the search for alternative fuels. Electric drive vehicles (EDVs) are one way of reducing vehicle emissions that contribute two-thirds of all air pollution in most cities. Some electric drive technologies are battery electric vehicles (BEV), hybrid electric vehicles (HEV) and fuel cell powered vehicles (FCV). To support the introduction of EDVs, Pacific Gas and Electric Company is playing a critical role in evaluating and developing new electric drive technologies. Through education programs, demonstration projects, and market infrastructure research, the company's support for EDVs will benefit our customers by ensuring a healthier environment Electric Drive Technologies Battery Electric Vehicle (BEV) An electric vehicle is a motor vehicle, such as an automobile, truck, or bus, which uses a rechargeable battery for fuel, replacing gasoline, diesel or other types of combustible fuels. Gone are the internal combustion engine and the transmission. A BEV utilizes an electric motor or, in some applications, more than one motor to propel the vehicle. The energy stored in the Electric Vehicle's rechargeable battery supplies power to a motor controller. The motor controller is a device that controls the amount of power supplied to the electric drive motor(s) based on the position of the accelerator pedal. Refueling an electric vehicle consists of connecting the vehicle to an outlet or charging device that is......

...Corporate Strategy Analysis: General Electric Co. (1981–present) Stanislav Bucifal Australian National University July 2009 Corporate Strategy Analysis: General Electric Co. (1981–present) Stanislav Bucifal Introduction The General Electric Company (GE) is widely regarded as one of the world’s most successful corporations of the 20th century. This paper aims to critically analyse the corporate strategy of GE during the period from 1981 to present under the leadership of two very different but equally influential CEOs—Jack Welch and Jeff Immelt. The essay is organised in four sections. The first section describes GE’s corporate strategy from 1981 to 2001 with Jack Welch as CEO, followed immediately by a critical analysis of Welch’s strategic approach in the second section. The third section then describes GE’s corporate strategy from 2001 to present with Jeff Immelt as CEO, followed again by a critical analysis of Immelt’s strategic approach in section four. 1. The Jack Welch period (1981–2001) When Jack Welch took up his post as GE’s CEO in 1981 he embarked on a radical transformation of GE’s strategy, ushering in a new era of performance management and internal efficiency. Welch’s profit guidance aimed for earnings growth of 1.5 times to double of the GDP growth rate and his management philosophy found its articulation in GE’s slogan—Speed, Simplicity, Self-Confidence (GE 1995). These values would reflect not only in the organisation’s......

...| Generator | | | | | | When a company such as Generator decides to invest in a foreign market with distinctly nondomestic cultural norms such as China and Thailand, it would be well served to investigate and develop a negotiation and communication strategy that will mitigate these differences in a way that will not unduly jeopardize the success of its new endeavors. While they considered the differences in the legality of their overseas standing, it is obvious that Generator failed to develop a plan that accounted for the cultural hurdles before entering into these partnerships. By entering into these partnerships they effectively mitigate the limitations of corporate ownership in these countries. In contrast, their lack of understanding and adapting to foreign ways of thinking has resulted in the potential alienation and humiliation of their partners. With their failure to proactively administer to these cultural differences Generator must now address these issues downstream. Ideally they would have fashioned their forward-looking communications in a manner that acknowledged the difference between Chinese and Thai culture and approached them from two different standpoints. By segmenting one country from the other they will have the opportunity to facilitate constructive negotiations that are culturally aligned with their intended audience. This would also encourage them to not group all Asian cultures together and repeat mistakes that they have......

...Case: Globalization at General Electric Summary: The closing case explores General Electric’s quest to become the number one or two company in global market for every business which it take part. General Electric (GE) is the largest industrial conglomerate in America, produces a wide array of goods and services, from medical equipment, power generators, jet engines, and home appliances, to financial services and even television broadcasting. Since 1985, GE earned over 40 percent of its revenues from international sales. Besides that, analysts estimate that by 2012, GE will be generating 55 to 60 percent of its business internationally. When GE was led by Jack Welch, to reach the goal, he sanctioned an aggressive and often opportunistic foreign direct investment strategy. In present, under the leadership of Jeffery Immelt, GE is moving towards seeing a more global corporation with an interest. The expansion of GE is mainly powered by dynamics economies of Asia. Question 1 GE has invested so aggressively in foreign expansion is due to the fact that they want to achieve their main goal which was to be number 1 or 2 globally in every business in which it participate. They took opportunities to exploit countries which having economic downturn. For example, in Europe from 1989 to 1995, they manage to invest $17.5 billion in the region, half of which was used to acquire some 50 companies; in 1995, when the Mexican peso collapsed in value, they purchase companies throughout Latin...

Gasoline-Electric Hybrid Car

...then sell four big, expensive luxury cars that only get 20 mpg (11.76 liters per 100 km)! when a car pulled up to the gas pump lately and been shocked by the high price of gasoline? As the pump clicked past $20 or $30, maybe you thought about trading in car for something that gets better mileage. Or maybe worried that the car is contributing to the greenhouse effect. The auto industry has the technology to address these concerns. It's the hybrid car. You're probably aware of hybrid. Any vehicle is a hybrid when it combines two or more sources of power. This is an improvement over the electric car, which uses gasoline engine along with electric motor powered by batteries. In the series system of the hybrid car engine driven generator is employed to recharge the batteries while the electric motor drives the car. Where as in parallel system the heat engine is directly connected to the electric motor. The key to a hybrid car is that the gasoline engine can be much smaller than the one in a conventional car and therefore more efficient. INTRODUCTION We might wonder why anyone would build such a complicated machine when most people are perfectly happy with their gasoline-powered cars. The reason is twofold: to reduce tailpipe emissions and to improve mileage. The emissions standards dictate how much of each type of pollution a car is allowed to emit in to atmosphere. The amount is usually specified in grams per mile (g/mi). The low emissions vehicle......

...engines with the pedal power of the rider. Hybrid vehicles are an alternative being used to decrease the emissions of vehicles and to decrease the amount of fossil fuels being used. Hybrid vehicles also cost less to operate because of the decreased fuel usage. The gasoline-electric hybrid car is a cross between a gasoline-powered car and an electric car. Hybrid vehicles are all around us. Most of the locomotives we see pulling trains are diesel-electric hybrids. According too How Cars Work, Cities like Seattle have diesel-electric buses these can draw electric power from overhead wires or run on diesel when they are away from the wires. There are two kinds of hybrids. The parallel hybrid has a fuel tank which supplies gasoline to the engine. But it also has a set of batteries that supplies power to an electric motor. Both the engine and the electric motor can turn the transmission at the same time, and the transmission then turns the wheels. In a parallel hybrid, both the electric motor and the gas engine can provide propulsion power. The other type is a series hybrid. In the series hybrid the gasoline engine turns a generator, and the generator can either charge the batteries or power an Hybrid Vehicles 3 electric motor that drives the transmission, so the gasoline engine never directly powers the vehicle.
