CONCEPT:

  • Current Loop As a Magnetic Dipole: A current-carrying circular coil behaves like a bar magnet whose magnetic moment is

M = NIA

Where N = number of turns in the coil, I = Current through the coil and A = Area of the coil

  • The right-hand thumb rule of circular currents: According to this rule if the direction of current in the circular conducting coil is in the direction of folding fingers of the right hand, then the direction of the magnetic field will be in the direction of the stretched thumb.

EXPLANATION:

  • According to the question, the direction of current in the circular current loop is in an anticlockwise direction, therefore the top face of the coil will behave as North pole according to the Right-hand thumb rule of circular currents.
