State three factors on which the magnitude of the force on a current-carrying conductor placed in a magnetic field depends. Can this force be zero for some position of the conductor?

Text Solution

Verified by Experts

The magnitude of force (F) acting on a conductor of length (l) and carrying a current (I) when placed in a magnetic field of magnitude (B) depends upon I, l and B as follows:
(i) `FpropI` (ii) `Fpropl` (iii) `FpropB`.
No force acts on such a conductor when it is placed parallel to the direction of magnetic field.
