Simple Design
Production of electricity
using wires and magnets is already an easy concept. Basically any magnet moving
near any conductor (wire) will induce some electrical force (voltage) in the
conductor. Making it work however, is a technical challenge. Often the amount of
electricity produced by movements of a magnet next to a wire is only a few
millivolts. Such low voltage is not enough for any thing. The technical
challenge is coming up with a design that produces more voltage. You will need
at least one volt (1000 millivolts) in order to light up a small light bulb.
The wooden generator project
is a successful attempt toward creating a simple design that is easy to
understand and produces 1 to 3 volts.
Simple and detail
instructions with clear pictures reduce
the chance of mistakes and increase the success rate.
When you spin the rotor, the magnet will
spin inside the box. This will induce a voltage in the coil of magnet
wire wrapped over the box. |
