is connected to an ammeter A primary coil is connected to a battery A current can be produced by a changing magnetic field First shown in an experiment by Michael Faraday Faradays Experiment. In general all industries are operating their machineries with induction motors.. All machines work on the principle of electromagnetism principle. . Whenever the current flowing thro a conductor , the magnetic field is produced around the conductor.. . Lenz's law . Induced current produces a secondary magnetic field that is always opposed to the primary magnetic field that induced it, an effect called . Lenz’s law. .. Self-inductance (L). The alternating current in the coil generates an alternating magnetic field that induces an . Presented by Beth Sassano CPC, . CPC-I, CCS-P, CPMA. .
