Question

A long wire carries a steady current. When it is bent in a circular form, the magnetic field at its centre is B. Now if this wire is bent in a circular loop of n turns, what is the magnetic field at its centre ?(A) nB (B) n²B (C) 2nB (D) 2n²B

Answer 1

The magnetic field at the centre of circular coil is measuring with each motion path.

When wire of length it bents into a new magnetic field.

In fact, the magnetic field at the center of the coil is B. It is then bent into a circular loop of n turns.

The magnetic field at the center of the coil will be nB. n2B. 2nB. 2n 2B of 35 A.
