Magnetic field intensity at the centre o...

Magnetic field intensity at the centre of coil of `50` turns, radius `0.5m` and carrying a current of `2A` is

A

`0.5 xx 10^(-5) T`

B

`1.25 xx 10^(-4) T`

C

`3 xx 10^(-5) T`

D

`4 xx 10^(-5) T`

Text Solution

Verified by Experts

The correct Answer is:
B
`B = (mu_(0) IN)/(2r) = (4pi xx 10^(-7) xx 2 xx 50)/(2 xx 0.5) = 1.25 xx 10^(-4) T`.
