Dynamo Effect

An electric current is induced when an electric wire is moved up and down between the opposite pole of a magnet

No current is produce when the wire a. is held stationaryb. when the magnet is removed.

The size of an induced current depends on i. the speed of moving wireii. the number of coils iii.the strength of the magnet

What is dynamo effect?

When a wire is moved up and down between the opposite poles of a magnet, an electric current is produced.

Energy Change of dynamo effect

Energy change from kinetic energy to electrical energy

1. Increase number of coils

2. Using a strong magnet

Strong magnet

Weak magnet

3. The wire is moved faster

Up and down is faster

Up and down is slower
