Magnetic field due to 0.1 A current flow...

Magnetic field due to `0.1 A` current flowing through a circular coil of radius `0.1`m and `1000` turns at the centre of the coil is

A

`2 xx 10^(-1) T`

B

`4.31 xx 10^(-2)T`

C

`6.28 xx 10^(-4)T`

D

`9.81 xx 10^(-4) T `

Text Solution

Verified by Experts

The correct Answer is:
C
As, `B = (mu_(0)NI)/(2r) = ((4pi xx 10^(-7) xx 1000 xx 0.1)/( 2 xx 0.1)) = 6.28 xx 10^(-4) T `
