Magnetic dipole moment is a

An iron bar of length $L$ has a magnetic moment $M$. It is bent at the middle of its length such that the two arms make an angle of $60^{\circ}$ with each other. The magnetic moment of this new magnet is:

Two magnetic poles have a pole strength of $0.01 \, A \cdot m$ each and are separated by a distance of $0.1 \, m$. What is the magnetic field at the midpoint between the two poles?

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

The magnitude of magnetic fields at a distance $r$ from the centre of a short bar magnet,in longitudinal position to transverse position,is in the ratio:

$A$ magnetic rod of length $L$ has a magnetic dipole moment $M$. If it is bent into a semicircle,what will be its new magnetic dipole moment?
