The plane of a circular coil is horizontal. It has 10 turns each of radius 8cm. A current of 2 A flows through it. The current appears to flow clockwise from a point above the coil. Find the magnitude and direction of magnetic field at the centre of the coil due to the current.

A circular coil is lying in a horizontal plane. The coil has 20 turns with each turn of radius 10 cm. For an observer above the coil, the current of 5 A appears to flow in the anticlockwise direction. What is the magnitude and direction of magnetic field at the centre of the coil?

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.

If current through a circular coil flows in clockwise direction, then the direction of magnetic field at the centre of the circular coil is………………to the plane of the coil, directed……………. .

A current of 5A is flowing through a 10 turn circular coil of radius 7cm . The coil lies in XY plane. What is the magnitude and direction of magnetic dipole moment associated with it?

Two concentric coil X and Y of radii 16cm and 10cm respectively lie in the same vertical plane containing the north-south direction. Coil X has 20 turns and carries a current of 16A, coil Y has 25 turns and carries a current of 18A. The sense of current in X is anti-clockwise and in Y, clockwise, for an observer looking at the coil facing west, Figure. Give the magnitude and direction of the net magnetic field due to the coils at their centre.

A current of 6A is flowing through a 20 turns circular coil of radius 5cm.The coil lies in the xy-plane. What is the magnitude and direction of the magneitc dipole moment assocaited with it?

A tightly wound 100 turn coil of radius 10cm is carrying a current of 1A . What is the magnitude of the magnetic field at the centre of the coil?
