Make your own transformer to change AC electricity from high voltage to low voltage or from low voltage to high voltage. The Transformer Bench is part of the larger Experiment Gallery on level 3.
Describe how moving electric charges produce magnetic forces and moving magnets produce electric forces.
Use the interplay of electric and magnetic forces to explain how motors, generators, and transformers work.
Describe how an electric current produces a magnetic force, and how this interaction is used in motors and electromagnets to produce mechanical energy.
Explain and calculate current, voltage and resistance, and describe energy transfers in simple electric circuits.
