1. Dynamo Effect

2. 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 stationary b.when the magnet is removed.

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

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

5. Energy Change of dynamo effect Energy change from kinetic energy to electrical energy

6. 1. Increase number of coils

7. 2. Using a strong magnet Strong magnet Weak magnet

8. 3. The wire is moved faster Up and down is faster Up and down is slower

9. Making a dynamo
