Electromagnetic induction explains why a second coil becomes energized when placed near a coil connected to AC. The alternating current in the first coil continually changes the magnetic field around it, and this changing field passes through the second coil. According to Faraday’s law, the changing magnetic flux through the second coil induces an electromotive force, so, if the circuit is closed, current flows and the coil energizes. The effect strengthens with closer proximity and better alignment because the magnetic flux linkage is greater. Capacitive coupling would transfer energy via electric fields and is not the main mechanism here. Magnetic resonance involves energy exchange at specific resonant frequencies rather than straightforward induction from a nearby powered coil. Mutual coupling is the relationship between two inductors, but the immediate phenomenon at play is induction from the changing magnetic flux.
