Two magnetic lines intersect ? Why ?
In the case of bar magnet, lines of magnetic induction
A bar magnet of length $10 \,cm$ and having the pole strength equal to $10^{-3}$ weber is kept in a magnetic field having magnetic induction $ (B)$ equal to $4\pi \times {10^{ - 3}}$ Tesla. It makes an angle of $30°$ with the direction of magnetic induction. The value of the torque acting on the magnet is
Define the intensity of magnetic field.
If a piece of metal was thought to be magnet, which one of the following observations would offer conclusive evidence
The magnetic moment of the arrangement shown in the figure is ............. $M$
