Answer:
Magnetic metalic elements
Many materials have unpaired electron spins, and the majority of these materials are paramagnetic. When the spins interact with e…
Composites
Ceramic, or ferrite, magnets are made of a sintered composite of powdered iron oxide and barium/strontium carbonate ceramic. Given t…
Rare-earth magbets
Rare earth elements have a partially occupied f electron shell. The spin of these electrons can be aligned, resulting in very strong magn…
