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

`5xx10^(4)`

C

`2xx10^(4)`

D

`5xx10^(3)`

Text Solution

Verified by Experts

The correct Answer is:
B
`phi=NBAcostheta`
`phi=20xx10^(3)xx10^(3)xx10^(-4)xx5xx10^(-4)xxcos60^(@)Wb," "phi=(1)/(2)xx10^(-3)Wb`
`phi=(1)/(2)xx10^(-3)xx10^(8)` Maxwell , `phi=5xx10^(4)` Maxwell
