What coild and capacitor to use in LC-circuit

[BRSUN]

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.

I am going to measure the waves using an oscilloscope

Thank you for your question. The power of the capacitor and the number of loops in the coil will depend on several factors, including the frequency of the circuit, the desired change in flux, and the distance at which the change in flux needs to be detected. In general, a higher capacitance and more loops in the coil will result in a larger change in flux, but this may not always be necessary or desirable.

To determine the best combination of capacitor and coil for your specific experiment, I would recommend using the formula for resonance in an LC circuit (1/√(LC) = ω), where ω is the angular frequency of the circuit. This will help you determine the ideal capacitance and inductance for your desired frequency.

Additionally, you may want to consider using a variable capacitor and a variable coil in your circuit to allow for adjustments and fine-tuning of the circuit. This will give you more control over the change in flux and the sensitivity of your experiment.

I also recommend consulting with a colleague or mentor who has experience with LC circuits and can provide guidance and assistance in selecting the appropriate components for your experiment. Good luck with your project!
