Maxwell's Equations

See electric and magnetic fields as one changing, connected system.

The four equations are compact source-and-response rules: charges and currents shape fields, while changing fields can themselves become sources. Together they predict electromagnetic waves.

A changing magnetic flux creates a circulating electric field. That is induction: the field relationship is spatial, not a wire-only rule.
