Essays on Electromagnetism

This video highlights the development of theory of interaction of electricity with magnetism. A number of scientists were involved in understanding, interpreting and validating electromagnetism with simple experiments involving current and magnetic elements. During September 1820, Ampere investigated magnetic effects of repulsion/attraction between like/unlike poles. He developed theory of electro-dynamics related to magnetism as interaction of current elements. Laplace was skeptical of his ideas while some other scientists like Fernel started thinking on converse patterns. Some other scientists like Jean Fernel focused on theory of production of electricity by magnetism and production of currents in conducting metals. Jean Fernel ...

Transport is a key factor of economy well as useful tool used for development of a society rather nation for its intensive use. Good transportation can create market and various social opportunities. There are various modes of transportations like train, bus, car, ship, aeroplane, etc. But fossil fuel, used in all modes of transportation, has become big concern in today’s world due to carbon emission causing environment pollution or global warming. So, the core idea of future transportation has become to diminish carbon emission and for this reason electricity and magnetism have become popular for their potential use in transport ...

Technological advancement as made the world to be a fully dynamic place where the sunrise marks the beginning of another tireless journey to invention, discoveries and innovations. As we are speaking, there are people who are working round the clock so as to come up with something that would change the world. Who is this person working round the clock and what is he/ she working on? Is his work going to bring a change in the transport sector? If so, how is the recovery going to be received, satisfy and fulfil its sole purpose? This are some of the questions ...

Wireless communication refers to transmission of data or signals via electromagnetic waves. In other words, it is a form of communication that does not involve the use of wires. Instead, radio and microwaves are used to transfer data or signal from one device to another. The first wireless transmission system was developed in early 20th century. This system used Morse code which was a combination of dots and dashes or long and short electric signals assigned to each letter of the English alphabet. The signals were sent and received via wires. This enabled transmission of text based information over a long distance. ...

Haunting is a common word bearing one or more meanings, depending on the context. One definition of haunting is continual memory to the mind that has a disturbing effect or arousal of strong emotions. These memories are unforgettable, and are commonly referred to as haunting memories. Second definition is recording of past event done on an environment like a household, battleground, or building. These recordings are capable of playing repeatedly when triggered in a manner similar to a film or a video. Psychologists believe that the presence of an individual can trigger playing back of these recordings. Details of how these recordings are made are not ...

Electricity and Magnetism in transport system.

The resultant energy from existing charged particles that are either static or in motion is called electricity and such energy can be used in homes, industries and in transport system. Whereas magnetism is a physical aspect that involves the electric charges, their motion and effect thus producing fields that repel and attract other objects (Kirkland, 2007). Electromagnetism plays an important role in our life and it is believed that it will change the future especially when it comes to transportation. Therefore electricity and magnetism can be considered to be inextricably linked in many cases; the essay will hence argue the ...

Introduction

Electromagnetism refers to the creation of a magnetic force from the movement of electrical charges. In order to find application in most electrical appliances, electromagnetism concerns the use of electric current to make electromagnets. This field of electricity is called Electrodynamics. It can also mean using magnetic field to induce an electric current. This field of electromagnetism is called Electromagnetic Induction. Almost all electrical appliances use one of the two types of electromagnetism mentioned above especially those with moving parts. This paper discusses the application of electromagnetism in a speaker.

Application of electromagnetism in a speaker

The speaker is basically an electronic transducer which converts electric energy ...

In order to understand the relationship between light, magnetism and electricity, it is necessary to understand electromagnetism force, since this is the basis upon which the relationship is embarked on. In this essence, it should be noted that it is impossible to have electricity, in the absence of magnetism. This is because electricity conduction is only achieved through magnetic transmission. Electricity, to start with, is the energy charge that is transmitted through the flow of electrons through a conducting agent from one point to the next. This is referred to as an electric current. One of the most essential things ...

Michael Faraday was born on 22 September 1791 in the southern part of London. Due to his disadvantaged background, he was not able to attend full education only achieving basic literacy (Faraday 1). At the age of 14, he apprenticed under a local bookbinder. For the next 7 years, he educated himself by reading books on a wide range of subjects mostly scientific (Hamilton 23; Scientific papers). In 1812, at the age of 20, Faraday received some tickets for a series of lectures conducted by the eminent scientist Humphrey Davy of the Royal University of Great Britain. He attended four lectures and ...
