| 1 | edu | What is eddy current when the magnetic flux is established in the core it tries to establish a current in the plane which is perpendicular to the direction of flux. this current is known as eddy current. to decrease this current the core is made up of thin plates. this eddy current increases the core loss of the machine. |

| 2 | chdd | What is eddy current Hi... As was said, the eddy current comes to existance when a conducter moves in a direction perpendicular to the magnetic flux lines. this produces current as well as a forces which opposes the movement. In Electrical machinery this effect is undesirable and techniques are utilzed to reduce this current and the resultant force. On the other hand there are growing applications of this phenomenon such as Focko Brake where this force is used to reduce the speed of a mooving conductor. Hope this Helped! |

| 4 | netlgc | What is eddy current An electric current induced within the body of a conductor when that conductor either moves through a nonuniform magnetic field or is in a region where there is a change in magnetic flux. It is sometimes called Foucault current. Although eddy currents can be induced in any electrical conductor, the effect is most pronounced in solid metallic conductors. Eddy currents are utilized in induction heating and to damp out oscillations in various devices. |
