3. Will magnets lose their power over time?
Do lose a very small fraction of their magnetism over time. But if elect the wrong materials and exceed the max work tempreture,magnet will lose magnetism forever.
4. Why are most neodymium plated or coated?
A: Neodymium magnets are mainly constructed of Neodymium, Iron and Boron. Iron can oxidize very easily when exposed to moisture and will rust over time.
