A straight wire of length 0.5 metre and ...

A straight wire of length `0.5` metre and carrying a current of `1.2` ampere is placed in a uniform magnetic field of induction 2 tesla. If the magnetic field is perpendicular to the length of the wire , the force acting on the wire is

A

2.4 N

B

1. 2 N

C

3.0 N

D

2.0 N

Text Solution

Verified by Experts

The correct Answer is:
B
`F = I l B = 1. 2 xx 0.5 xx 2 = 1.2 N`
