Teaching Minds-On Experiments on Electromagnetism in Secondary Schools Lorentz force Paperclip-motor
This simple electric motor is constructed from small AAA battery, wire coil, two paper clips and a magnet as shown.
Start the motor by placing the magnet on the battery directly above the
coil and giving the coil a small spin. If all these things are correct,
your little motor should be spinning around at a pretty fast rate. Try
holding it upside down. The motor should spin in the opposite
direction. Try turning the magnet upside down and see which direction
the motor spins.
