AI Thread Summary
For the LC-circuit project, the focus is on selecting an appropriate capacitor and coil configuration to emit detectable electromagnetic waves within a 2-meter range. The discussion highlights the importance of providing more context about the application to better tailor the recommendations. The user intends to measure the emitted waves using an oscilloscope for an extended essay. A variable range of coils is desired to experiment with different configurations. The conversation emphasizes the need for clarity on detection capabilities and specific goals for the circuit design.

I am building an LC-circuit. I was wondering what power of capacitor and loops of coil would be best to use to create a change in flux, which was not to big but could be detected in a range of 2 meters from source. A range of coils would also be nice as I will have it as a variable in my experiment.

Do you want to use your circuit as an emitter of electromagnetic waves, or do you want to detect the magnetic field?
"could be detected" is a very vague term - with good equipment, you can detect nearly everything.

More context would be interesting. Is there some application you have in mind?
 
I am building it to emit electromagnetic waves. It's for an extended essay I am writing.

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
