A simple DC motor is shown below. In this motor, the armature {the part that spins) consists of a single loop {coil}. oou noercloclcwise a} Using your knowledge of how DC motors work, state the direction of rotation of the coil (armature). {1 ma rk) b} Explain why, for a DC motor, the current to the coil in the armature must be reversed twice during each rotation. (2 marks} c] What device reverses the current in the coil of the armature? Explain why it is required. (1 mark} d} Suppose that the two field magnets were reversed (eg. turned around) so that the magnetic north pole is on the right. Explain how the armature would move. (1 mark)
