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

`2xx10^(-1)T`

B

`4.31xx10^(-2)T`

C

`6.28xx10^(-4)T`

D

`9.81xx10^(-4)T`

Text Solution

Verified by Experts

The correct Answer is:
C
As, `B=(mu_(0)Ni)/(2r)=((4pixx10^(-7))xx1000xx0.1)/(2xx0.1)=6.28xx10^(-4)T`
