What are eddy current braking work and how do they work in braking systems? Thanks :D?

Question

I know it has something to do with Lenz's law and Faraday's law? But I'M still unsure. Websites haven't been very helpful either.

Answer 1

Eddy current brakes are made from a large electrically conducting object moving through a stationary magnetic field. An electric current is generated just as happens when a wire moves across a magnetic field, but in a large conductor, the current finds its own path in roughly circular patterns within the conducting object. The circulating current creates a magnetic field that is attracted to the stationary magnetic field. That magnetic attraction provides the braking force. The braking energy is converted to heat in the moving object. The brake can also be constructed with a stationary conducting object and a moving magnet. The magnet can be either a permanent magnet or an electromagnet. The movement can be either in a straight line or circular, With circular motion, the magnetic field needs to be on the perimiter of the motion.
