First developed in the 1970âs and 80âs, super magnets are the strongest type of permanent magnets ever made, are ferromagnetic, meaning that like iron they can be magnetized, and have Curie temperatures that are below room temperature.
Before we look at electromagnets let's recap bar magnets. Bar magnets are permanent magnets. This means that their magnetism is there all the time and cannot be turned on or off. They have two poles: Bar magnet. 1  north pole (or north-seeking pole). 2  south pole (or south-seeking pole).
