Term that refers to how a changing magnetic field can stimulate a voltage and current in a loop of wire.
What must change in order for electromagnetic induction to occur?
Move magnet near wire, move wire near magnet, change current in nearby wire
What are the three ways that voltage can be induced in a wire?
Input and output are opposite
What is the primary difference between an electric motor and an electric generator?
Electric energy can be carried along wires, but how can it be carried across empty space?
No, energy can never be stepped up
Can an efficient transformer step up energy?
To reduce current flow and energy loss
Why is power transmitted at high voltages over long distances?
