Question

at the centre of a circular current carrying coil the magnetin field is uniform and perpendicular to the plane of coil​

Answer 1

Answer:

Magnetic field due to current carrying wire can be comprehended by using magnetic filed lines which are concentric circles with centre at the axis of the conductor and its direction can be determined by Maxwell's right hand grip rule.

Thus the magnetic field is uniform and perpendicular to the plain of coil.
