A circular coil of radius 5 cm has 500 turns of a wire. The approximate value of the efficient of self-induction of the coil will be ……

The coefficient of self inductance of a coil is

A circular coil of radius 5 cm and has 50 turns carries a current of 3 ampere. The magnetic dipole moment of the coil is

A circular coil of diameter 7cm has 24 turns of wire carrying current of 0.75A . The magnetic moment of the coil is

A coil is wound on a rectangular frame. Keeping the number of turns per unit length constant, if the linear dimensions of the coil are doubled then the coefficient of self induction of the coil will become.

A circular coil of radius 5 cm has 169 turns carries a current of 2.6 A . The magnetic induction at a point on the axis at a distance of 12 cm from the centre of the coil is
