How could you work out the direction that the motor will turn

Electric motors use the motor effect. A simple electric motor can be built using a coil of wire that is free to rotate between two opposite magnetic poles. When an electric current flows through the coil, the coil experiences a force and moves. One side moves up and the other side moves down. The direction of the current must be reversed every half turn, otherwise the coil comes to a halt again. This is achieved using a conducting ring split in two, called a split ring or ‘commutator’.

50 inches should be the resultant vector

its a 5.5 n
