A circular coil of wire consisting of $100$ turns, each of radius $8.0 c m$ carries a current of $0.40 A$ . What is the magnitude of the magnetic field $B$ at the centre of the coil?

Magnetic field, $B = \frac{μ_{o}}{4 π} \frac{2 π n I}{r}$
n=no. of turns, $I$ =current, $r$ =radius of coil
So, $B = 3.1 \times 10^{- 4} T$

A circular coil of wire consisting of 100 turns, each of radius 8.0 cm carries a current of 0.40 A. What is the magnitude of the magnetic field B at the centre of the coil?

Magnetic field, B=μo4π2πnIrn=no. of turns, I=current, r=radius of coilSo, B=3.1×10−4T
