Define magnetic dipole moment of a current carrying coil.

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 N turns is made of a conducting wire of a certain length . When a current I is sent through it , the magnetic moment is p , Another coil of 2N turns is made with the same wire and the same current is sent through it . The magnetic moment becomes p'. If p : p ' = n : 1 , what is the value of n ?

A uniform conducting wire of length length 10a and resistance R is wound up into four turn as a current carrying coil in the shape of equilateral triangle of side a. If current I is flowing 4 through the coil then the magnetic moment of the coil is
