In the following figures,the lines of magnetic induction due to a magnet $SN$ are given by:

$A$ cylindrical magnetic rod has length $5 \ cm$ and diameter $1 \ cm$. It has uniform magnetization $M = 5.3 \times 10^{3} \ A/m$. Its net magnetic dipole moment is nearly (take $\pi = 22/7$):

The intensity of magnetization of a bar magnet is $5.0 \times 10^{4} \text{ A m}^{-1}$. The magnetic length and the area of cross-section of the magnet are $12 \text{ cm}$ and $1 \text{ cm}^{2}$ respectively. The magnitude of the magnetic moment of this bar magnet is (in $SI$ unit):

$A$ wire of magnetic moment $M$ is moulded according to the figure. What is the new magnetic moment?

What is the pole strength of a bar magnet? Express the magnetic dipole moment in terms of pole strength.

The effective length of a magnet is $31.4 \, cm$ and its pole strength is $0.5 \, Am$. The magnetic moment,if it is bent in the form of a semicircle,will be.....$A m^2$.
