In 1822, French physicists Arago and Lussac found that when a current was passed through a wire wound in it, it could magnetize the iron in the wire. This is actually the original discovery of the electromagnet principle. In 1823, Strkin also did a similar experiment: he wound 18 turns of bare copper wire on a U-bar that was not a magnet bar. When the copper wire was connected to a volt battery, it wound around U The copper coil on the iron rod creates a dense magnetic field that turns the U-bar into an "electromagnet." The magnetic energy on this electromagnet can be magnified many times than that of permanent magnet, it can absorb the iron 20 times heavier than it, and when the power is cut off, the U-shaped iron can not absorb any iron, Ordinary iron bars. Strkin's electromagnetism was invented, so that people see the bright prospects of electricity into magnetic energy, the invention quickly spread in the United Kingdom, the United States and some Western European coastal countries. In 1829, the American electrician Henry made some innovations in the Stringer electromagnet device. The insulated conductor replaced the bare copper conductor, so there was no need to worry about being shorted too close by the copper conductor. Since the wires are insulated, they can be wound together in tight loops. The more intense the loops, the stronger the magnetic field. This greatly increases the ability to convert electrical energy into magnetic energy. By 1831, Henry had tried out a newer electromagnet, which, despite its small size, could suck up a ton of iron. The invention of the electromagnet also makes the power of the generator greatly improved.
