The given figure shows a DC motor model used by a student to study electromagnetism.
The two ends of the coil are fixed to a pair of curved elastic metal strips. The metal strips are connected to the power supply with a rheostat.
(i) State the direction of rotation of the coil when viewed from the front.
(ii) The student is still testing on the feasibility of using the metal strips in the model. What is he trying to achieve?
