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

Force on a current carrying conductor placed in a magnetic field is `F = Bil sin theta ` in the case ` theta =90^(@)`
`therefore F =BIL =2 xx 1.2xx1/2 =1.2 N`
