A force of 8 N acts on a rectangular conductor 20 cm long placed perpendicular to a magnetic field. Determine the magnetic field induction if the current in the conductor is 40A.

Text Solution

Verified by Experts

Force acting F=8N
Length of conductor l=20 cm=0.2 m
Current l=40 A
Magnetic field induction B=?
We know F=BIL
`implies B=F/11=(8N)/(40A times 0.2 m)=1 Tesla`
