Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
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.’
- ‘This corresponds to the opposing nature of Lenz's Law.’
- ‘A simple experiment can be used to help students develop an understanding of the induction of eddy currents and Lenz's Law.’
Mid 19th century: named after Heinrich F. E. Lenz (1804–65), German physicist.
