9. The circuit of a simple DC electric motor is shown in the figure that follows. It consists of a current carrying coil as the armature. The coil is square

with the sides of 0.05 m. The coil is in a uniform magnetic field of strength0.005 T. A conventional current of 3.0amps flows through the coil in the direction shown in the diagram by the arrows. a) When the coil is in the position shown in the diagram, indicate the direction of the force on side P of the wire. b) What happens to the direction of the force on side P when the direction of the current is reversed? c) Give two different ways that the armature could be made to spinfaster. d) Differentiate between an electric motor and an electric generator.
