| Abstract | Resonance is one of the recurring themes in physics and, as such, is important in research applications and in explaining many everyday phenomena. Students often encounter resonance during studies of simple harmonic motion, sound, mechanical waves and AC circuits. Alternatively, or in addition, resonance can be demonstrated in the context of magnetic (and mutual) induction. Previously, Mak incorporated two LC resonators to show transfer of energy between the two via electromagnetic induction and electromagnetic radiation. In this article, by contrast, one coil is driven at varying frequencies while a second one experiences magnetic induction as part of an LC circuit. Magnetic induction is discussed, followed by a description of the demonstration. (Contains 1 figure.) (ERIC). |
