Can someone tell me if I’m on the right track? Explain why Ferromagnetism is sometimes considered to be a special case of paramagnetism. Ferromagnetism is a special case of paramagnetism in that as with paramagnetism, ferromagnetism moves from an area of weak magnetism to an area of high magnetism when placed in a strong external magnetic field, the atoms align in the direction of the magnetic and creates a strong attraction. Even though with ferromagnetism, the unpaired electron aligns in...
