11. The diagram below shows a simple d.c. motor connected to a battery, a switch. (Note that only the nearest poles of two magnets are shown). switch a. Onthe diagram, draw arrows to show the direction of the magnetic field between the magnetic poles, and the direction of the current in the circuit. b. On the diagram, clearly label any forces on the coil (the loop of wire) once the switch is closed. c. State which way the coil of the motor will rotate when the switch is closed, when viewed from the position X (clockwise/counterclockwise?) d. State two things which could be done to increase the speed of rotation of the coil. e. Why is a commutator necessary to make a motor work when the current entering it is continuous (not alternating)
