- A current flowing through the conductor establishes a magnetic field around the conductor. This effect works both way so that the conductor will flow in a conductor which is moved through a magnetic field.
- You ca easily demonstrate electromagnetic current generation with a coil of wire and a small magnet.
- Connects the leads of the coil to a meter designed to sense microamperes.
- Insert a steel nail through the coil and stroke the magnet back and forth across the coil. The meter will indicate a few microamperes each stroke.
- The polarity of the current will reverse on the back strokes.
Want a readymade generator????
Just rotate the shaft of a small DC motor. Most such motors produce a potential difference of up to several volts….You can add a propeller to make a wind powered generator…
