What is the magnitude of magnetic force per unit length of a wire carrying a current of 5 A and making an angle of `30^(@)` with the direction of a uniform magnetic field of `0.1` T ?

A

`0.45N//m`

B

`0.35N//m`

C

`0.25N//m`

D

`0.55N//m`

Text Solution

Verified by Experts

The correct Answer is:
C
`F =Bil sin theta`
`therefore F /l =BI sin theta =0.1 xx5xx sin 30^(@) =0.25 N //m`
