What is the difference between Gauss’s law in electrostatics and Gauss’s law in magnetism ?
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
Write difference between electrostatic and magnetics :
Verify the Ampere’s law for magnetic field of a point dipole of dipole moment ${\rm{\vec M = M\hat k}}$. Take $\mathrm{C}$ as the closed curve running clockwise along : the $\mathrm{z}$ - axis from $\mathrm{z} = \mathrm{a} \,>\, 0$ to $\mathrm{z = R}$;
In which direction does a free hanging magnet get stabilized ? Explain.
The ultimate individual unit of magnetism in any magnet is called
