Strong Electromagnet is a device that energizes to generate electromagnetism. It converts electrical energy into magnetic energy, and then converts magnetic energy into kinetic energy (electrical energy→magnetic energy→kinetic energy). Let's take a look now!

1.Strong Electromagnet refers to neodymium magnets. Compared with ferrite magnets, alnico magnets, and samarium cobalt magnets, its magnetic properties greatly surpass other magnets. Neodymium magnets can absorb 640 times their own weight, so NdFeB is often called a powerful magnet by outsiders.
2. The temperature resistance of Strong Electromagnet is below 80 degrees. We just put the strong magnets on the fire for a few minutes. After cooling, you put it next to the iron block and find that it has lost its magnetism and can no longer attract. The reason why a strong magnet is magnetic is because the iron atoms in the strong magnet are arranged regularly. After heating, the original arrangement of iron atoms is disrupted, thus losing the original magnetism. Likewise, we can demagnetize strong magnets in other ways.
