Answer to Question 1

Electromagnetic induction occurs when two coils of wire are placed in close proximity to each other. As AC current is passed through the first coil it creates flux lines as the current increases from zero to peak. When the current returns from peak back to zero, the flux lines will collapse. When the flux lines collapse, they pass the 2nd coil of wire and create a current flow in that coil. The current is created in the second coil without any electrical connections between the two coils.
