A loop of wire having 50 turns carries a current of `10A` in anticlockwise direction. If diameter of loop is `10cm`, what is the magnitude and direction of magnetic moment of current loop?

What is magnetic moment of a current loop?

The magnitude of magnetic moment of the current loop in the figure is

The magnitude off magnetic moment of the current loop in the figure is

A planar loop of irregular shape encloses an area of 8.5 xx 10^(-4) m^2 and carries a current of 10 A. The sense of flow of current appears to be clockwise to an observer. What is the magnitude and direction of the magnetic moment vector associated with the current loop?

A circular loop of radius R carries current I_2 in a clockwise direction as shown in figure. The centre of the loop is a distance D above a long, straight wire. What are the magnitude and direction of the current I_1 in the wire if the magnetic field at the centre of loop is zero?
