Moving magnet and conductor problem

The moving magnet and conductor problem is an experiment that demonstrates the connection between electricity and magnetism. To do this experiment you need a magnet, conductor (like a piece of copper wire) and a power source (like a battery). First you put your magnet next to the conductor and nothing happens. Then you start to move the magnet towards and away from the conductor, and you will see an electric current start to flow in the conductor. This is because when you move the magnet, it creates a magnetic field (an invisible energy field) which induces an electric current to flow in the conductor, just like twisting a rubber band will create energy which can make a toy car move. This shows that electricity and magnetism are connected, and that is the moving magnet and conductor problem.
