A coil of area `5cm^(2)` and having 20 turns is placed in a uniform magnetic field of `10^(3)` gauss. The normal to the plane of the coil makes an angle of `60^(@)` with the magnetic field. The flux in Maxwell through the coil is:

A

`10^(5)`

B

`5 xx 10^(4)`

C

`2 xx 10^(4)`

D

`5 xx 10^(3)`

Text Solution

Verified by Experts

The correct Answer is:
B
`phi = NBA cos theta`
`phi = 20 xx 10^(3) xx 10^(-4) xx 5 xx 10^(-4) xx cos 60^(@ Wb`, `phi = (1)/(2) xx 10^(-3) Wb`
`phi = (1)/(2) xx 10^(-3) xx 10^(8)` Maxwell, `phi = 5 xx 10^(4)` Maxwell
