Description
Demonstrations prove that when two coils are placed near each other, any change in the flow of electric current in the primary coil will induce a current in the secondary coil. Experiments explore the factors that increase the induced current, illustrating the relationship between the number of rings in a coil and the ratio of voltage applied to the amount of electricity induced.
