What type of substances would make better permanent magnets, ferromagnetic or ferromagnetic. Justify your answer. 

Answer:

Ferromagnetic substances are better permanent magnets than ferromagnetic substances because in the first case, the spins due to all unpaired electrons are alligned in the same direction. On the other hand, in ferromagnetic substances, the electronic spins are alligned both in the parallel and antiparallel directions in unequal number.
