What is the force on a wire if its length (L ) makes an angle `'theta'` with the magnetic field (B) when the current passing in the wire is l?

Text Solution

Verified by Experts

`F=Bqv sin theta or F=B l l sin theta`, where T is current
Here=B magnetic induction,q=charge,v=velocity of the charge and `'theta'` is the angle between direction of field and velocity.
