The elements lie in d-block or f-block of periodic table and they have large number of unpaired electron which contribute to spin dipole moment so they have large dipole moment and are strongly magnetized. Example:- Fe, Co, Ni, Gd, Dy Since ferromagnetic material is a strongly magnetized the magnetic field line converge when they passed […]


In paramagnetic material magnetic dipoles already exist due to spin of unpaired electron in an atom. In paramagnetic material magnetic dipoles are randomly oriented but when magnetic field is applied such dipoles align parallel to external magnetic field.                              Due to positive susceptibility the flux density inside the paramagnetic material increases. In a paramagnetic material […]
