Consider a wire carrying a steady current, I placed in a uniform magnetic field B perpendicualr to its length, conside the cahrges inside the wire it is known that magnetic forces do no work. This implies that.

Options

A. motion of charges inside the conductor is unaffected by B since they donot absorb energy
B. some charges inside the wire move to the centre as a result of B
C. if the wire moves under the influence of B, no work is done by the force
D. if the wire moves under the influence of B, no work is done by the magnetic force on the ions, assumed fixed within the wire

Answer

D
