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 of I ampere is flowing through each of the bent wires as shown the magnitude and direction of magnetic field at O is

A circular segment of radius 20cm subtends an angle of 60^@ at its centre. Figure A current of 10A is flowing through it. Find the magnitude and direction of the magnetic field produced at the centre.
