The electromagnetic brake was invented by a French engineer named Georges Hilaire Marie Claude Renior in the 1950s. The automatic circuit breaker was invented by Thomas Edison in the late 19th century.
The Lenz Law is "An induced electromotive force generates a current that induces a counter magnetic field that opposes the magnetic field generating the current." It was invented by a Russian Physicist named Heinrich Lenz.
Michael Faraday invented electromagnetic on 29TH of August 1831. ADDED: He didn't "invent" it but discovered its principles.
Electromagnetic waves were predicted, by calculations, by James Clerk Maxwell. Later, different parts of the electromagnetic spectrum were either discovered or confirmed to be electromagnetic waves by various scientists.

The electromagnetic pump was invented by Nikola Tesla in the late 19th century. Tesla's design used electromagnetic principles to move and pump fluids efficiently without any moving parts, relying on the magnetic field created by electrical currents to drive the flow of liquid.
