I can describe how different factors affect the size and direction of an induced current or potential.
Show transcript
A magnet moving relative to a wire connected in a complete circuit can cause a current to flow in the wire.
A magnet moving in the opposite direction relative to a wire induces a current in the opposite direction.
A magnet moving relative to a wire can cause a potential difference across the wire called the induced potential.
Induced potential is proportional to mag. field strength and the relative speed of movement between a wire and a magnet.
For a magnet moving relative to a coil, the induced potential is proportional to the number of turns of wire in a coil.
