Faraday's Law Calculator

Compute induced EMF in a coil from Faraday's law of electromagnetic induction: EMF = -N·dΦ/dt.

Frequently Asked Questions

What is Faraday's law?

EMF = -N·dΦ/dt. The induced EMF in a coil equals the rate of change of magnetic flux, times the number of turns, with a sign from Lenz's law.

What is a weber?

The SI unit of magnetic flux: 1 Wb = 1 T·m² = 1 V·s.

Why does AC work?

Rotating a coil in a magnetic field continuously changes its flux, inducing alternating EMF. That's how generators produce grid power.
