I have a function generator that will emit an audio tone. I have two coils of wire and I'm trying to couple the audio signal from the primary coil to the secondary coil. The output of the secondary coil will be fed to an audio amplifier I bought from jaycar ( https://www.jaycar.com.au/low-cost-mains-powered-stereo-amplifier/p/AA0472 )which I would hear the tone with some headphones. A circuit of what I'm trying to build is shown below with labels and the inductance values of the coils.
A few things I'm unsure about my design. Will this setup damage my function generator? Should I account for impedance matching? Should I have the two parts of the circuit connected to a common ground?
