TL;DR

Lc resonance with high Q factor. Inductor with non magnetic core and air gap

Consider Inductor with air gap and solid metal core made from material with relative magnetic permeability 1 regardless of temperature (such as copper or aluminium).
There is Air gap between coil and metal core

Please Also consider Eddy currents in the solid metal core.
The Inductor is connected with capacitor in

Series LC circuit

Parallel LC circuit

Is it possible under certain values of frequency and capacitance to obtain lc resonance with high q factor?

TL;DR Summary: Lc resonance with high Q factor. Inductor with non magnetic core and air gap

Is it possible under certain values of frequency and capacitance to obtain lc resonance with high q factor?

No. The eddy current heating of the core will be significant, and so will preclude a high Q. But then your definition of high Q may be different from mine.

An LC tank circuit could be driven to oscillate at its resonant frequency, but the active oscillator element would need to make up the energy lost to the eddy currents in the core.

Let's say Is it possible with certain values of Capacitance and Frequency to obtain Resonance with Q above 20 for the given LC Circuit?

Let's say Is it possible with certain values of Capacitance and Frequency to obtain Resonance with Q above 20 for the given LC Circuit?

Why would you say that?
You could design it to have a Q of 20.
What are the dimensions of the coil and the core?
Why is Q relevant?
