Problem
A straight copper rod of length 15 cm is placed in a uniform magnetic field of 0.50 T. The rod carries a current of 8.0 A and makes an angle of 60∘ with the direction of the magnetic field.
Solve the following, showing all steps clearly.
(a) Calculate the magnitude of the force acting on the rod.
(b) If the same rod is replaced by another rod of length 30 cm while all other conditions remain unchanged, determine the new force.
(c) Comment briefly on the effect of doubling the length on the force obtained in part (b).
