Split ring ammutator- keeps the coil rotating
Brushes- connect the slip rings to the circuit.
When a wire is placed in a magnetic field, it experiences a force.
The force is greatest when the wire is perpendicular to the magnetic field
The force is 0 when the wire is parallel to the magnetic field because the magnetic field is not cut.
The force acts on both sides of the coil. this causes the coil to turn when a current passes through.
