Answer:

20cm

Explanation:

A coil wire comprises of 5 turns, it has a current of 2mA

A net magnetic field at the center of B is equal to Mu over 40 end fractions times T

The radius of a coil of wire with N turns is r = 0.28 m. A clockwise current of Icoil = 1.0 A flows in the coil,

Therefore 40/2mA = 20
