A wire of length 1 m is kept perpendicular to a magnetic field of `0.98` T. What is the current folowing through the wire if a force of 1 kg weight acts on the wire

A

`1 A `

B

`10 A `

C

zero

D

`5 A`

Text Solution

Verified by Experts

The correct Answer is:
B
`F = Bil sin 90^(@) =Bil`
`therefore I =(F)/(Bl) =(1xx 9.8)/(0.98xx1) =10A`
