on video Eddy Current Brakes - Introduction, types and application

 

We know that electromotive force & current will generate when the magnetic flux is flowing throughout a coil changes. Similarly, once the magnetic flux is passed throughout a solid coil, then it will induce current & emf. So the induced current through the conducting body is called the eddy current. This current is named an eddy current because of the flow of the current look like eddies/whirlpools. This article discusses an overview of an eddy current – working with applications.

What is Eddy Current?

Eddy current definition is; the flow of current that is induced in any solid conducting body once the magnetic flux is supplied throughout it. Once the conductor encounters a change within the magnetic flux, then the free electrons present in the conductor will experience a magnetic force. So the magnetic force effect on the free electrons will move in the eddies or small loops form which is called the eddy current.

The main properties of eddy currents are; these are only induced within the conducting materials, they are distorted by different defects like corrosion, edges, cracks, etc. So this is used in aerospace, power & petrochemical-based industries for detecting damages & metal cracks.

Eddy Current Working Principle

The eddy current working principle is to generate eddy currents within a conductive material. So this can be achieved by connecting a coil to an AC generator which drives an alternating magnetic field. The flow of current induced by this magnetic field in the conductive material will generate a magnetic field by itself in opposition to the alternating magnetic field based on Lenz's law.

This current is induced current within a conductor whenever a conductor is simply exposed to a varying magnetic field because of the relative motion of the conductor as well as the field source or because the field changes with time. So this can cause electrons to flow in a circular form in the conductor's body. These circulating currents (eddy currents) have inductance & induce magnetic fields. So these fields can cause attractive, propulsion, repulsive & drag effects.

When the applied magnetic field is stronger or the electrical conductivity of the conductor is greater, or the field changes faster, then the developed currents are greater that are developed & produced fields are greater. This current generates heat & electromagnetic forces like all electric currents. The generated heat can be used for induction heating whereas electromagnetic forces are used for creating movement, levitation, or to provide the very strong braking effect.

Eddy Current Theory

The induced eddy current's magnitude is measured by using Faraday's law of magnetic induction. Based on the second law of Faraday's, the emf induced can be written simply as the speed change of magnetic flux with respect to time will give an increase to induced e.m.f within the conductor,
