[0032] Further, the magnetic attraction device 4 can be replaced with an electromagnet, and the size of the magnetic force can be adjusted by adjusting the size of the current in the electromagnet. The electromagnet is a device that generates electromagnetism by electrification. A conductive winding that matches the power is wound outside the iron core. Such a coil with current has magnetism like a magnet. It is also called an electromagnet. It is usually made into a strip or a hoof shape to make the iron core more easily magnetized. In addition, in order to make the electromagnet demagnetize immediately after power-off, soft iron or silicon steel material with fast demagnetization is often used to make it. Such an electromagnet has magnetism when electrified, and the magnet disappears after power-off. The electromagnet has extremely wide application in our daily life, and its invention has greatly improved the power of the generator.
