how are eddy currents produced?
Every metal or a conducting substance has a large number of free electrons which move randomly in the metal.
When this peice of metal is subjected to a changing magnetic feild or flux the electrons exeperience force and move in circular paths of different radii..
These circular paths resembles eddies or whirpools in liquids which are created on ne disturbance in/on water surface..
hence these currents are termed as eddy currents.......
