This topic has proved itself to be a hard one in, in terms of looking it up online. I'm interested in simple harmonic motion, in specific that of a tuning fork vibrating between two electromagnetic devices, a microphone ad a detector. My main interest in it is to write a lab report about an experiment I have conducted on a tuning fork. I understand physically the notion of resonance (a frequency such that it pushes the fork always in just the right time to amplify it vibrations) but the mathematical side is somewhat difficult. So in terms of the electromagents in relation with the turning fork, can anyone please explain it to me in a bit more mathematical sense? Also the effect of damping by placing a magnet in between the forks. Thanks.
