Ferromagnetic solids are……. By an external magnetic field

A

weakly attracted

B

strongly repelled

C

weakly repelled

D

strongly attrated

Text Solution

Verified by Experts

The correct Answer is:
4
Because of the alignment of all the individual magnetic moments of large groups of atoms to give highly megnetic domains. Example `Fe,Co,Ni` and `CrO_(2)`. Unlike, paramagnetic substances they show permanent magnetism even when the applied magnetic fiels is removed.
