SIMPLE ELECTRIC MOTOR WHAT IS AN ELECTRIC MOTOR? • Turns electricity into motion (the motor part of the name) SIMPLE MOTOR • We need • Battery - for the electricity • Copper wire to carry electricity • Magnet to push the wire • Paper clips to support STEP 1 • Make a coil from the wire. • Leave two ends sticking out STRIP THE WIRE • Take the plastic coating completely off one end • Take the plastic coating half off the other end • This is the tricky bit. SET UP THE MOTOR • Bend the paper clips into shape to support the coil. • Join one paper clip to each end of the battery to make the circuit • Bring the magnet close to the coil and give the coil a spin. WHY DOES IT SPIN? • The electricity flowing through the wire makes magnetism. • The magnetic field from the magnet pushes against the magnetic field from the coil. • As the coil is light and free to spin, while the magnet is not, the coil spins
