Paramagnetic substances are weakly attracted by magnetic fields. Ferromagnetism Ferromagnetic substances can be permanently magne- tized as randomly oriented electron spins align coop- eratiyely in domains. Ferro- magnetism is much stronger than paramagnetism. flfrgnmenl of ens-errors spins in a finemngneiic substance. Diamagnetlsm In diamagnetic substances all electrons are paired. Diamagnetic sub- stances are yery, very weakly repelled by magnetic fields, a much weaker interaction than either paramagnetism or ferromagnetism. ...
