Eddy currents are swirling electric currents that are induced in a conductive material when it is exposed to a changing magnetic field.
Eddy currents are produced when a conductive material is exposed to a time-varying magnetic field, typically caused by the movement or change in direction of a magnet or a changing current in a nearby coil.
Eddy currents have several practical applications, including metal detection, non-destructive testing, and magnetic braking in trains and roller coasters.
In electrical equipment, eddy currents can cause energy loss and heating, which can reduce the efficiency of the equipment and potentially cause damage if not controlled.
Yes, eddy currents can be controlled or reduced by using materials with low electrical conductivity, laminating conductive materials, or using magnetic shielding to redirect the magnetic field.
