Question

The direction of force on a current carrying conductor placed in a magnetic field can be reversed by reversing the direction of current flowing in the conductor. True/False?

Open in App
Solution

The force experience by a current carrying conductor placed in a magnetic field is :
F=I(l×B)=IlBsinθ
If the direction of current flow is reversed then the v will also change its direction and eventually the direction of force will also be reversed.

Hence True.
