How does a current loop behave like a magnetic dipole? Draw the magnetic field lines for a current loop to support your answer.

Answer»

Solution :When a current is passed through a closed LOOP , a magnetic field is produced along the axis of the loop and it behaves like a magnetic dipole of moment m = IA. On looking through the axis, if current flows clockwise that FACE will be the south POLE and the other face will be the NORTH pole.
