Electromagnetic Induction — three ways to learn it.

Move a magnet through a coil and watch an EMF appear from nothing. Read how Faraday and Lenz explain it, animate the changing flux in 3D, then test yourself. Pick any door — they all teach the same chapter.

Lecture & walkthrough

The complete written lesson — magnetic flux Φ = BA cosθ, Faraday's law of induction (ε = −N dΦ/dt), Lenz's law and energy conservation, motional EMF (ε = BLv), self and mutual inductance, and how the AC generator and the transformer put induction to work.

Interactive lecture

As you scroll, a live 3D panel animates every idea: push a bar magnet into a coil and watch the galvanometer needle flick, reverse it and see the current flip — Faraday's and Lenz's laws, alive on screen.

Run the induced-EMF experiment on a safe, virtual bench: change how fast the flux through a coil changes and measure the EMF it drives, confirming Faraday's law and plotting EMF against the rate of change of flux.
