A law stating that the direction of an induced current is always such as to oppose the change in the circuit or the magnetic field that produces it.
- By Lenz's law, the current swirls in such a way as to create a magnetic field opposing the change; to do this in a conductor, electrons swirl in a plane perpendicular to the magnetic field.
- The DLR team used electromagnetic levitation, which exploits an EM field to provide both levitation, through Lenz's law, and heating, through surface eddy currents.
- This is created because of a principle known as Lenz's law.
Mid 19th century: named after Heinrich F. E. Lenz (1804–65), German physicist.
