Figure shows an equilateral triangle ABC of side l carrying currents as shown, and placed in a uniform magnetic field B perpendicular to the plane of triangle. The magnitude of magnetic force on the triangle is

A

`ilB`

B

`2ilB`

C

`3ilB`

D

zero

Text Solution

Verified by Experts

The correct Answer is:
a
The equivalent figure can be redrawn as
Force on `AB=ilB`, Froce on BCA=2ilB
in opposite direction to that on BA.
Hence, net force`=2ilB-ilB=ilB`
