Question

A circular coil lies in the plan has 5 turns each of 4cm radius, 4 ampere current flows through it, which is clockwise to us. Find the magnitude and direction of the magnetic field at the centre of the coil.

Answer 1

hey mate!

Magnetic field at x=0(at centre) due to circular current carrying wire is.

B° =mu nod N I / 2R

N = number of turns

R= redius

B° = 4 π ×10 ^-7 ×5 × 4 /2 ×2×10-^2

B°. = 20π ×10^-5T
