Dynamo Effect

Dynamo Effect. No current is produce when the wire is held stationary when the magnet is removed. An electric current is induced when an electric wire is moved up and down between the opposite pole of a magnet. The size of an induced current depends on the speed of moving wire

  1. Dynamo Effect

  2. No current is produce when the wire • is held stationary • when the magnet is removed. An electric current is induced when an electric wire is moved up and down between the opposite pole of a magnet

  3. The size of an induced current depends on • the speed of moving wire • the number of coils • 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 Weak magnet Strong magnet

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

  9. Making a dynamo
