Faraday's Law of Induction

Electromagnetism · 1831

Equation: ∇×E = −∂B/∂t
Field: Electromagnetism
Named After: Michael Faraday
Symbols: E electric field · B magnetic field · ∇× curl (circulation around a point) · t time
Year: 1831

Significance

A changing magnetic field stirs up a circulating electric field — the principle inside every generator, transformer, and induction cooktop. Third of Maxwell's four equations.
