Copper winding coil action:

2. Tuning and frequency selection
Characteristics of copper core coils
1. Inductance
The inductance L represents the inherent characteristics of the coil itself and has nothing to do with the magnitude of the current. Except for the special inductance coil (color-coded inductance), the inductance is generally not marked on the coil, but marked with a specific name.
2. Inductive reactance
The magnitude of the resistance of the inductive coil to the alternating current is called inductive reactance XL, and the unit is ohm. Its relationship with inductance L and AC frequency f is XL=2πfL
3. Quality factor
The higher the Q value of the coil, the smaller the loop loss. The Q value of the coil is related to the DC resistance of the wire, the dielectric loss of the skeleton, the loss caused by the shield or iron core, and the influence of the high-frequency skin effect. The Q value of the coil is usually tens to hundreds.
4. Distributed capacitance
The capacitance that exists between turns and turns of the coil, between the coil and the shield, and between the coil and the plate is called distributed capacitance. The existence of distributed capacitance reduces the Q value of the coil and deteriorates the stability, so the smaller the distributed capacitance of the coil, the better.
