How Does an Inductor or Loading Coil Work ?
Much of the data below also applies to inductors in equipment
The most common questions are:
What does the coil do? A normal physically small (physically small compared to antenna length or wavelength)
What determines current distribution in a loading coil? Current distribution is determined by stray capacitance to the outside world and the impedance terminating the loading coil. The current in any inductor would be equal at each end except for displacement currents. Displacement currents are “imaginary currents” that flow through a capacitance. A changing electric field is tied to these currents.
