The difference between a magnet and a magnet: 1. A magnet is generally a metal ore that is naturally magnetic and is an ore magnetized by the earth's magnetic field. 2. A magnet is a metal alloy that is magnetized by humans. 3. The magnet is made of ore, which is a permanent magnet from nature and does not require current. The magnet may be a permanent magnet that is processed, possibly an electromagnet. The electromagnet requires current to generate a magnetic field, the current is cut off, and the electromagnet magnetic force disappears.
