An electromagnet is a device that is energized to produce an electromagnet. The core is wound with an electrically conductive winding adapted to its power, and the coil, which is energized with electric current, is magnetic like a magnet, which is also called an electromagnet. It is usually made in the shape of a bar or a shoe to make the core easier to magnetize. In addition, in order to enable the electromagnet to be demagnetized immediately after power failure, the electromagnet is usually made of soft iron or silicon steel materials which are demagnetized quickly. When the electromagnet is electrified, the electromagnet has magnetism, and the magnetism disappears along with the electrification after the electromagnet is powered off. In the nine-grade physical teaching materials (north teachers, teaching versions), experiments about factors related to the strength of the electromagnet magnetism are researched, and the experiments adopt a variable control method to research the factors affecting the strength of the electromagnet magnetism, including the relationship between the number of turns of a coil and the relationship between the strength of current.
