Ferromagnetism :-
- Generally Ferromagnetism is a physical phenomenon that is seen
in the magnetic material's in which the magnetic moments of all the
atoms in one domain which are lying in very small region of a
crystal and they are pointing in the same direction.
- They have permanent dipole moment present in domains.
- Here in the presence of external magnetic field Atomic dipoles
in ferromagnetic substances are oriented in the same
direction.
- Here also The magnetic dipole moment is large and is in the
direction of the magnetizing field
- Examples:- Iron , Nickel and cobalt are the example of
ferromagnetism materials.
Magnetized materials :- These are any material having magnetic
force and can attract or repel other materials, particularly metals
so called magneticmaterials.
examples :- these are also iron nickel cobalt zinc etc.
