Question

If a bar magnet is kept near a current-carrying material, will a force act on it​

Answer 1

Answer:

Since, the magnet is small (i.e, dimension of magnet<<a), we can assume that the magnetic field due to current carrying wire at the location of magnet is uniform.

And, we know that in a uniform field , net force on a magnet is zero. And since field B is perpendicular to magnetic axis , and not parallel, hence there will be a net torque acting on the magnet given by

M × B

Answer 2

Answer:

invisible force of and rays
