Eddy currents are the currents induced in the body of a conductor due to change in magnetic flux linked with the conductor.
Applications of eddy currents are:
a) Electromagnetic damping - Designing dead beat galvanometer
b) Induction furnace
c) Magnetic brakes
d) Electric power meters
e) Induction motor
To minimise eddy currents, the metal core to be used in an appliances like motor is taken in the form of thin sheets. Such a core is called laminated core. The planes of these sheets are arranged parallel to the magnetic field so that they cut across eddy current paths.Large resistance between the thin sheets confines the eddy current to the individual sheets. Hence eddy currents can be reduced to a large extent.
