(i) Low coercivity and high permeability
(ii) Gauss’s Law in magnetism: The net magnetic flux through any closed surface is zero.
\(\oint\) B.ds = 0
Gauss’s Law in electrostatics: The net electric flux through any closed surface is \(\cfrac{1}{ε_0}\) times the net charge.
\(\oint\) E.ds = \(\cfrac{q}{ε_0}\)
The difference between the Gauss’s law of magnetism and that for electrostatic is a reflection of the fact that magnetic monopole do not exist i.e. magnetic poles always exist in pairs.
