A solenoid is 1.0 metre long and it has 4250 turns. If a current of 5.0 ampere is flowing through it, what is the magnetic field at its centre `[mu_(0)=4pixx10^(-7)"Weber"//amp-m]`

A

`5.4xx10^-2 Wb//m^2`

B

`2.7xx10^-2 Wb//m^2`

C

`1.35xx10^-2Wb//m^2`

D

`0.675xx10^-2Wb//m^2`

Text Solution

Verified by Experts

The correct Answer is:
B

`B=mu_0nI=4pixx10^-7xx4250xx5`
`=60xx4.25xx10^(-4)=2.7xx10^(-2)T`.
