Question

Why Paramagnetic substance's susceptibility is positive?

Answer 1

Paramagnetic materials have a small, positive susceptibility to magnetic fields. These materials are slightly attracted by a magnetic field and the material does not retain the magnetic properties when the external field is removed.

Answer 2

$\sf{Explanation}$
$<b>$
⏩Diamagnetic substances have a negative relative permeability (susceptibility); paramagnetic substances have positive.Ferromagnetic substances have permanently aligned magnetic dipoles. In the presence of the external field the sample moves toward the strong field, attaching itself to the pointed pole.
