WebAboutTranscript. Eddy currents are current loops formed over conductor surfaces due to changing magnetic flux. They are useful in induction heating, levitating, electromagnetic damping, and electromagnetic braking. They can be minimized by adding slots in the conductor surface & laminating. Created by Mahesh Shenoy. WebJan 30, 2024 · The applications of Eddy Currents are as follows: 1. Braking Mechanism in Trains. Trains have metal wheels that run over the metallic tracks. When brakes are applied, the metal wheels of the trains get exposed to a magnetic field which induced eddy currents in the wheels. Thus, the trains slow down due to the magnetic interaction between the ...
