Magnetic field produced at the centre of...

Magnetic field produced at the centre of circular coil having radius 0.1 m and 2 turns is _____ if `1/(4pi)A` current passes through it.

A

`10xx10^(-6)T`

B

`0.1xx10^(-6)T`

C

`1xx10^(-6)T`

D

`0.01xx10^(-6)T`

Text Solution

Verified by Experts

The correct Answer is:
C
`B=(mu_(0)NI)/(2a)`
`thereforeB=(4pixx10^(-7)xx2xx1)/(2xx0.1xx4pi)" "thereforeB=1xx10^(-6)T`
