Induced Current and Eddy Current

Click For Summary
SUMMARY

Eddy currents and induced currents are fundamentally related concepts in electromagnetic induction. Induced currents occur when there is a change in magnetic flux linked with a circuit, resulting in an induced electromotive force (emf) as described by Faraday's law. Eddy currents, a specific type of induced current, form in conductive materials, such as metal plates, when they oscillate within a magnetic field, creating a whirlpool effect. Both types of currents follow Lenz's law, which dictates their direction, but eddy currents are distinct in their formation and behavior compared to induced currents in closed circuits.

Homework Statement



I want to know whether Eddy current and Induced Current are same?

Homework Equations





The Attempt at a Solution


1)When flux linked with a circuit changes, an emf is induced in the circuit and this emf is called induced emf and the current is called induced current. The direction of current is given by Lenz law.
2)Now, let me come to Eddy current. When we consider a metal plate oscillating between the poles of a magnetic field, an induced current is set up in the metal in the form of whirlpool and hence called Eddy current and this Eddy current sets up its own magnetic field opposite to the magnetic field of poles.
The direction of induced current is given by Lenz law.
So it makes me to think the induced current formulated by Faraday in Electromagnetic induction(1) and Eddy current(2) are same. Am i right , revered members?

Yes, they are the same in the sense that eddy currents are specific examples of induced currents.

In many cases, induced currents are produced in conducting wires that are part of a circuit. In such cases the induced currents are not called eddy currents.

However, induced currents can also be easily produced in conductors of any shape. When the conducting material is spread out over an extended area or volume, the induced currents are called eddy currents.
 
Thanks TSnY.
