Question
A wire of length L is placed in a magnetic field B; If the current in the wire is I, the maximum magnetic force on the wire is
- B/IL
- BIL
- IL/B
- BL/I
Hint:
BIL
The correct answer is: BIL
Force on a conductor (F) =BILsinθ
If θ=90∘,FMax=BIL i.e., the direction of current and magnetic field are perpendicular to each other, then force is maximum.
