Eddy currents are currents which circulate in conductors like swirling eddies in a stream. They are induced by changing magnetic fields and flow in closed loops, perpendicular to the plane of the magnetic field.

What is eddy current examples?

Popular equipment such as stationary exercise bikes are a great example of eddy currents in action. Programming the bike to simulate an uphill climb increases the drag between the non-magnetic conductor and the permanent magnet in the bike making it more difficult to keep peddling.

What are eddy currents your answer?

An eddy current is a current set up in a conductor in response to a changing magnetic field. They flow in closed loops in a plane perpendicular to the magnetic field. ... Eddy currents transform more useful forms of energy, such as kinetic energy, into heat, which isn't generally useful.
