Define the pole strength of a magnet and write its $SI$ unit.
(N/A) The pole strength of a magnet is a measure of the ability of a magnetic pole to attract or repel other magnetic poles. It is defined as the force experienced by a unit north pole placed at that point in a magnetic field.
Mathematically,if a magnetic pole of strength $m$ experiences a force $F$ in a magnetic field $B$,then $F = mB$.
The $SI$ unit of pole strength is Ampere-meter,denoted as $A \cdot m$.
