Motors & Generators: Electromagnetic Induction
Purpose
To observe the mechanical energy produced from electrical energy.
Description
Small coil of wire, connected to a C-cell battery, spins above a magnet.
- Make sure coil's side wires are straight and along the coil's axis of
symmetry.
- Give coil a "kick start" to overcome friction.
- If coil will not continue to rotate, check all connections for any corrosion. If
necessary: scrap off any corrosion on coil's side wires. [One of the side
wires has its topside's varnish coating scrapped off, while the other has its
"bottom-side" scrapped off. In this manner we have simulated
alternating current, so that the force on the bottom half of the coil does not
change direction (as coil spins).]
