Write any five properites of ferromagnetic materials

Explanation

(i)They are strongly attracted by magnetic field.
(ii) They are strongly magnetized in the direction of the external magnetic field.
(iii) The magnetic field lines are highly concentrated inside the substance.
(iv) `chi` is large positive.
(v) `mu_r gt gt 1`
(vi) Above the curie temperature, its susceptibility varies inversely proportional to the excess of temperature.
(vii) They exhibits magnetic hysteresis.
