D Correct answer
Explanation

Electromagnetic induction, discovered by Michael Faraday, is the principle behind electric generators. When a conductor moves through a magnetic field, it induces an electromotive force. Storage cells and dry cells store chemical energy, while testers measure electrical properties but don't generate it.
