The Ring Launcher Experiment and Eddy Currents

What are eddy currents? The video focuses upon the demonstration of the concept of Eddy Currents and the application of Lenz Law, using a device called- RING LAUNCHER https://youtu.be/u4pFiJOJdQ8 Eddy currents are loops of electrical current induced within solid conductors by a changing magnetic field in the conductor according to Faraday’s law of induction. Eddy … Continue reading The Ring Launcher Experiment and Eddy Currents
