If a current I flows through a square current loop, then find the magnitude of the magnetic field at its center.

A wire of length L is bent around in the form of a coil having N turns of same radius . If a steady current I flows through it in a clockwise direction, find the magnitude and direction of the magnetic field produced at its centre.

A current I is flowing through the loop , as shown in the figure . The magnetic field at centre O is

A current loop in a magnetic field

A copper wire of length 7 metre is bent to form a circular loop. If i current flows through the loop, find out the magnitude of magnetic moment of the loop.

A current l flows through a closed loop as shown in figure .The magnetic field at the centre O is

A circular loop of radius 9.7 cm carries a current 2.3 A. Obtain the magnitude of the magnetic field at the centre of the loop .
