Magnetic field lines show the direction along which a small magnetized needle aligns. If magnetic monopole existed, how would the gauss’ law of magnetism be modified?

State Gauss's law for magnetism.

Magnetic field lines are the visualization of magnetic field.Write any three properties of magnetic field lines.

A bar magnet of magnetic moment 1.5J//T lies .aligned with the direction of a uniform magnetic field of 0.22 T? What is the torque on the magnet if it is aligned opposite to the direction of magnetic field?
