Problem
A straight wire of length 0.25m lies horizontally along the East–West direction and carries a steady current of 10A from West to East. The wire is placed in a uniform magnetic field of 0.5T that is directed vertically downward.
(i) Calculate the magnitude of the force acting on the wire.
(ii) State the direction in which the wire will tend to move.
(iii) If the current is reversed while the magnetic field remains unchanged, what will be the new direction of motion? Give reason for your answer.
