A magnet of magnetic moment $M$ and pole strength $m$ is divided in two equal parts, then magnetic moment of each part will be
$M$
$M/2$
$M/4$
$2M$
Some equipotential surfaces of the magnetic scalar potential are shown in the figure. Magnetic field at a point in the region is
The magnetic field lines due to a bar magnet are correctly shown in
Below figures $(1)$ and $(2)$ represent lines of force. Which is correct statement
A magnetic needle is kept in a non-uniform magnetic field. It experiences
Many of the diagrams given in Figure show magnetic field lines (thick lines in the figure) wrongly. Point out what is wrong with them. Some of them may describe electrostatic field lines correctly. Point out which ones.
