Question

Sketch the magnetic field lines for a current-carrying circular loop near its centre. Replace the loop by an equivalent magnetic dipole and sketch the magnetic field lines near the centre of the dipole. Identify the difference.

✓

Answer

As in loop magnetic field lines pass thorough the center but in case of magnet dipole the magnetic field lines does not pass through center or even meet at center point.
