Teaching Minds-On Experiments on Electromagnetism in Secondary Schools

Lorentz force
Turning coil between magnets

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