Electromagnetic Induction

Magnetism and Electromagnetism Electromagnetic Induction If an electric current can create a magnetic field (Oersted, 1820), could a magnetic field create an electric current?\ \ This question captivated scientists for a decade until, in 1831, English physicist Michael Faraday and American physicist Joseph Henry independently discovered the answer: yes — but only if the magnetic field is changing. \ A steady magnetic field does nothing; a changing one generates a voltage. \ This phenomenon, called electromagnetic induction, is the principle behind every electrical generator, transformer, and wireless charger on the planet. Key topics covered: - the following methods - equation form - Strength of the magnetic field - Number of turns in the coil - Speed of change Part of the Ïntermediate Science" series.
