(i) When paramagnetic substances are placed in a magnetic field most of the magnetic filed lines prefer to pass through them. It shows `mu` is more than 1 i.e. `B//H gt 1 or B gt H.`
[B inside the material is larger than air.]
(ii) In ferromagnetic material the magnetic field lines prefer to pass through them.
It shows `mu gt gt 1 or B//H gt gt 1 rArr B gt gt ` H and B magnetic field density inside material is much larger than air.
