Components of a Simple dc electric motor

A Motor with a loop of wire inbetween the two magnets A DC current The force acts downwards and the wire turns vertical and gets stuck as it cannot rotate anymore. The split ring commutator reverses the direction of the current and makes the rotation continue A split ring commutator is just a conducting ring with a gap between the two halves. As it rotates, the part of the commutator that is touching each contact chagnes every half turn.
