Question

Calculate the magnitude of the magnetic induction due to a circular coil of 400 turns and radius 0.05 m, carrying a current of 5 A, at a point on the axis of the coil at a distance 0.1 m.

Answer 1

Data : N = 400, R = 0.05 m = 5 × 10^-2 m, 

I = 5 A, z = 0.1 m, 

μ₀ /4π = 10^-7 T∙m/A 

The magnitude of the magnetic induction,
