If a bar magnet of pole strength $m$ and magnetic moment $M$ is cut equally $4$ times parallel to its axis and $3$ times perpendicular to its axis then the pole strength and magnetic moment of each piece are respectively

Options:

Answer:

Solution:

Pole strength $m$ is directly proportional to cross-sectional area.

$m^{'} = \frac{m}{5} M^{'} = \frac{M}{5 \times 4}$
