Take, for example, the reciprocal electrodynamic action of a magnet and a conductor. The observable phenomenon here depends only on the relative motion of the conductor and the magnet, whereas the customary view draws a sharp...

    A generator works by a magnetic field inducing a voltage into a coil of wire. Important points to note are that the voltage increases as the number of turns of wire on the coil becomes larger and the size of the coil and the strength of the magnetic field increase. The magnetic field (or the coil) needs to be in constant motion to produce/induce the electricity into the coil. This can be done by moving the magnet or by moving the coil - the effect is the same. The coil (or the magnet) needs to...

  • The use of electricity and magnetism in transportation
    Kevin Williams Project 1 The use of electricity and magnetism in transportation When Benjamin Franklin discovered electricity, it was probably one of the biggest discoveries known to mankind. Even though our dependence of electricity is a lot, however at the same time it’s easy to forget how dependent we actually are on it. Electricity always has and always will play a huge part in our everyday life. It’s hard to imagine humanity without it. When it comes to transportation, it is going to...

  • Faraday’s Inventions Then and Now
     Faraday’s Inventions Then and Now People find it strange that Faraday is the man who gets credit for the discovery of such brilliant work. Mostly because this humble man was “in no sense a mathematician”, and almost everyone describes him as ‘mathematically illiterate’. He never learned any mathematics and his contributions to electricity were purely that of an experimentalist.” (Connor & Robertson, 2001). But yet, it was Faraday's work which led others after him to deep mathematical...

    Not much over a hundred years ago, electricity, except in the form of lightning, was an unknown force. Its discovery was due to Michael Faraday, the great English scientist. On one occasion, about 1830, he was showing one of his early experiments to a distinguished company at the Royal Institution in London. He showed that when a magnet was brought suddenly near a coil of wire, a slight current of electricity was produced in the wire. Afterwards a lady said to him, "But, Professor Faraday, even...

    Vincent Phelps Mr. Anderson English 10 December 2012 Cell Phones of Death Skeptics have been saying cell phones cause dangerous side effects. As a result, some people claim that when magnetic waves are sent from cell phones, the waves have an allergic reaction on them. Others are saying these same waves caused their cancer. However, I have found virtually no studies that support these claims with scientific evidence. This is the reason for my choice of policy. The policies in regards...

  • Magnets and Coils - 1024 Words
    Magnets. How do they work? How does the number of coils affect electromagnetism? Hypothesis: When there is a flow of moving electrons, a magnetic field is created. We use the equation F = NIlB (Force = Number of coils x Current x Length of Wire x Magnetic Field Strength) to work out the magnetic force produced in a wire when there is an electric current present. Using this equation we can see that increasing the length of the wire (amount of coils) gives a larger force. So increasing the...
