The magnetic field at the centre of the current carrying coil :

The value of the magnetic field induction at the centre in the given figure will be (The coil is made of a uniform wire and is connected with two long straight wires. Assume r as the radius of coil).

Find the magnitude of magnetic induction at a point 0.06m from the centre and along the axis of a circular coil carrying a current of 2 A. Also calculate the magnitude of magnetic induction at the centre of the coil. Given: Number of turns in the coil = 20 Mean radius of the coil = 0.05 m.

A long wire carries a steady current, it is bent into a circle of 1 turn and magnetic field at the centre of the coil is B. It is then bent into a circular loop of n turns. The magnetic field at the centre of the coil will be

How does the strength of the magnetic field at the centre of circular coil of wire depend on [i] the radius of the coil, [ii] the number of turns of wire in the coil, and [iii] the strength of current flowing in the coil ?
