Electromagnetic induction
The science behind something you encounter, use, or wonder about.
The useful idea
- The useful idea
Electromagnetic induction or magnetic induction is the production of an electromotive force (emf) across an electrical conductor in a changing magnetic field.
- How it works
Michael Faraday is generally credited with the discovery of induction in 1831, and James Clerk Maxwell mathematically described it as Faraday's law of induction.
- Why it matters
Lenz's law describes the direction of the induced field.
Why this matters
Look for Electromagnetic induction the next time you notice this pattern in everyday life.
