A magnet is a magnetizable substance, but industrial magnets are not magnetic from the start. So, how to make a magnetizable substance magnetized? This can be achieved in several ways:
1. Use another magnet that has been magnetized: place the magnet that has been magnetized next to the magnet that needs to be magnetized, and then move the magnet slowly until the magnet that needs to be magnetized is completely magnetized.
2. Use current: Wind the magnet that needs to be magnetized with a wire, and then pass the current to make the magnet magnetized.
3. Using a magnetic field: Place the magnet that needs to be magnetized in a strong magnetic field, such as an electromagnet or a permanent magnet, to make the magnet magnetized.
No matter which method is used, care should be taken to protect the magnet from strong heat or mechanical shock, so as not to damage the magnetism of the magnet.
