Magnetic Field Opposite Direction
1,217 wordsThe phenomenon called electromagnetic induction was first noticed and investigated by Michael Faraday, in 1831. Electromagnetic induction is the production of an electromotive force (emf) in a conductor as a result of a changing magnetic field about the conductor and is a very important concept. Faraday discovered that, whenever the magnetic field about an electromagnet was made to grow and collapse by closing and opening the electric circuit of which it was a part, an electric current could be ...

1,746 wordsDiamagnetic's was discovered by Michael Faraday in 1846, but no one at the time thought that it could lead to any appreciable effects. William Thomson (Lord Kelvin), referring to levitation as the problem of 'Mohamed's coffin, ' had this to say: 'It will orally be impossible ever to observe this phenomenon, on account of the difficulty of getting a magnet strong enough, and a diamagnetic substance sufficiently light, as the [magnetic] forces are excessively feeble. ' Fields strong enough to lift...

Magnetic Field Generate Electricity
2,438 wordsPlanning Aim and hypotheses According to Flemings Rule, electricity is generated when movement occurs in the magnetic field. Alternatively, switching direction of the magnetic field also works. Alternating current is a good way of alternating the field direction. The electricity generated, of in the other words, the electromotive force, is measured in volts. By varying different parts of the apparatus, the EMF output could also vary. The aim of this investigation is to establish a connection bet...

Hydrogen Bomb Nuclear Fusion
2,740 wordsFusion reactions are inhibited by the electrical repulsive force that acts between two positively charged nuclei. For fusion to occur, the two nuclei must approach each other at high speed to overcome the electrical repulsion and attain a sufficiently small separation (less than one-trillionth of a centimeter) that the short-range strong nuclear force dominates. For the production of useful amounts of energy, a large number of nuclei must under go fusion: that is to say, a gas of fusing nuclei m...

Earths Magnetic Magnetic Field
1,778 wordsThe Role of Magnetic Stimuli in Animals In as early in the year 1855 Minddendorf proposed the idea of broad front, one-direction migration also suggested a means of orientation, that birds were capable of detecting the magnetic poles and of maintaining their bearing therefrom. Since then many similar ideas have continued to pop up at random intervals (Carthy 56). An immediate difficulty is the lack of any structure or tissue that could possibly react to the magnetic field. In the year 1948, the ...

Earths Magnetic Magnetic Field
1,384 wordsINTRODUCTION: The magnetic south and north poles of the earth create magnetic field lines in which these bacteria travel. These bacteria were found to contain iron, which is comparable to ferromagnet's or magnetite produced synthetically. This iron is found to line up to the magnetic field lines similar to how a compass works. Many of the principles of magnetism can be explained by observing these bacteria. NARRATIVE: The physical principles behind magnetic bacteria rely on the earths magnetic f...
