WebJan 26, 2024 · Magnets are made by exposing ferromagnetic metals like iron and nickel to magnetic fields. When these metals are heated to a certain temperature, they become permanently magnetized. It's also possible to temporarily magnetize them by using a variety of methods you can try safely at home. WebWhat we do know is that a Magnet field is generated by the motion of electrostatic charges within the the magnet itself. The electric charges being electrons. The electrons move in a coherent and synchronized fashion which causes a strong magnetic field to be projected out from the magnet. What we do not know is what that field is made up of.
