SUMMARY
This discussion focuses on the application of Lenz's law in understanding electromagnetic induction when an electromagnet is activated near a wire loop. Participants analyze the effects of changing magnetic flux on the induced current within the loop, specifically addressing the scenarios when the electromagnet is switched on and off. The right-hand rule is emphasized as a critical tool for determining the direction of the induced current. The consensus is that when the electromagnet is deactivated, the external magnetic flux decreases, resulting in a counterclockwise induced current in the wire loop.
