what are eddy currents write their two applications
Eddy currents are circular electric currents produced in a conductor when it is placed in a changing magnetic field. These currents flow in closed loops inside the conductor.
They are also called Foucault currents.
How eddy currents are formed
When the magnetic field around a metal object changes, electric currents are induced inside the metal due to electromagnetic induction.
Two applications of eddy currents
Electric brakes in trains and lifts
Eddy currents create opposing forces that help slow down or stop moving vehicles smoothly.
Induction heating and induction cooktops
Eddy currents produce heat in metal utensils, which is used for cooking and industrial heating.
Other uses
Speedometers
Metal detectors
Energy meters
Eddy currents are useful in many electrical devices, but they can also cause energy loss in transformers and motors if not controlled properly.
