A wire length `6.28m` is bent into a circular coil of 2 turns. If a current of `0.5A` exists in the coil, the magnetic moment of the coil is, in `Am^(2) :`

A wire of length 6.28 m is bent into a circular coil of 2 turns. If a current of 0.5 A exists in the coil, the magnetic moment of the coil is, in A-m^2

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

A wire of length 2 m carrying a current of 1 A is bend to form a circle. The magnetic moment of the coil is (in Am^(2) )

A circular coil of radius 10 cm and 100 turns carries a current 1 A. What is the magnetic moment of the coil ?

A circular coil of radius 10 cm and 100 turns carries a current 1A. What is the magnetic moment of the coil?

A wire of length 2 m carrying a current of 1 A is bend to form a circle. The magnetic moment of the coil is (in A-m^(2) )

The electric current in a circular coil of two turns produced a magnetic induction of 0.2 T at its centre. The coil is unwound and then rewound into a circular coil of four turns. If same current flows in the coil, the magnetic induction at the centre of the coil now is
