Define magnetic dipole moment of a current carrying coil.

Define magnetic dipole moment for a current carrying circular loop.

The direction of magnetic moment of a current carrying circular coil is

A current carrying coil represents

The magnetic moment of a current (i) carrying circular coil of radius (r) and number of turns (n) varies as

The ratio of magnetic field at the centre of a current carrying circular coil to its magnetic momnts is x. If the current and radius both are doubble the new ratio will become

The magnetic field at the centre of the current carrying coil

The magnetic moment of a current carrying loop whose circumference with radius 'r' is equal to the perimeter of square with length / is

The magnetic induction at the centre of a current carrying circular coil of radius 10cm is 5sqrt(5) times the magnetic induction at a point on its axis. The distance of the point from the centre of the coil in m is
