History of the Study of Magnetism

History of the Study of Mag light upism Because charismatic fields were non discovered until recently, the news report of how they were discovered is quite interesting, and informative. 1.1 The spying of Magnetic Fields We begin by giving an observational history of the development of electromagnetic scheme. As stated, people had gigantic cognize that magnetic fields existed, exclusively the only known source of these fields were permanent magnets, and no link was actualize to electricity. In the early 1800s, Hans Christian Oersted began to suck the connection betwixt electricity and magnetism. Oersted did most of his work employ compass needles, scarcely we will derive the existence of magnetic fields, and their relation to electricity, utilize more familiar systems-stream carrying wires. Consider ii current carrying wires foot race mate to one another. A current is manifestly a collection of moving charges. Traditional electric theory predicts that, since th e net charge on each(prenominal) wire is zero, on that straits is no interaction between the two wires. Experiments in the 1800s, however, showed a surprising result: the wires were actually attracted to each other! The canvas was repeated, with the currents running in opposite committals, with the result that the wires were mutually repelled. match situations are depicted below. Figure 1.1 Figure 1.1: Parallel wires carrying current, in both parallel and antiparallel directions. In each illustration an attractive or repulsive force is felt by each wire.

The overlarge arrows indicate direction of curr ent, while the teensy arrows indicate the d! irection of the force felt by each wire. This experiment set up that there was some frame of connection between magnetism and electricity, but a fewer more distinctions had to be made to generate a limpid definition. Firstly, if a metal shred (a conductor) were placed between the two wires, it had no effect on the phenomenon. Since conductors shield...
