Q)

# Magnetic field lines are always nearly normal to the surface of a force magnet at every point. (This fact is analogous to the static electric field lines being normal to the surface of a conductor at every Point ) Why?

$\begin{array}{1 1} \mu < < 1 \\ \mu > > 1 \\ \mu =1 \\ \text{None of the above } \end{array}$

This is because the value of permeability for ferromagnetic substance is always greater than 1 $( \mu > > 1)$
Answer : $\mu > > 1$
