SUMMARY
The discussion centers on the interaction between alternating current (AC) and magnetic fields, specifically how a current-carrying conductor in a magnetic field induces a variable force. When AC is passed through a conductor, it generates a variable magnetic field that can induce a force on nearby objects. This phenomenon is exemplified by the buzzing sound of an activated AC relay, which occurs due to the attraction between two iron pieces driven by this variable force. The induced force is directly proportional to the instantaneous current flowing through the conductor.
