Consider a tightly wound 100 turn coil of radius 10 cm, carrying a current of 1A. What will be the magnitude of the magnetic field at the centre of the coil? 10–4 10–3

Question

Accepted Answer

(a) 6.28 × T — Given, Number of turns in the coil = 100 Radius of coil = 10 cm Current flowing through the coil = 1A Therefore, µ IN Magnetic field at the center of the coil B = 2r r = 10cm = 0.1m 4π×10–7×1×100 B = 2×0.1m

Answer

(B) 6.28 × T 10–4 10–2

Answer

(C) 6.68 × T

Answer

(D) 6. 82 × T
