coil between magnets
The coil lies
between the poles oftwo magnets. The
current flows in opposite directions along the two sides of the coil.
to Fleming’s left-hand rule, one side is pushed up and the other side
down. In other words, there is a turning effect on the coil. With more
the coil, the turning effect is increased. Many electric motors use
turning effect principle.
