What is Inductor? - Fixed, Variable, Audio-Frequency ...
https://electronicscoach.com/inductor.html
In some application, we require variable inductors which possess values which change with the requirement. Such types of the inductors are known as variable inductors. In applications such as phase shifting or tuning circuits, we need to have variable inductors in the circuit. The inductance of the inductor can be varied by changing the number of turns wounded on an iron core.

The RF (radio-frequency) chokes are designed to block RF frequency while allowing DC and audio frequency. Variable Inductor. As the name suggests, these inductors are designed to have variable inductance. This variable inductor is designed in more than one possible way. The most common design of variable inductors is having a movable ferrite core.

is adjustable or variable. Adjustable inductors change their inductance by a movable inner core. As the core moves to the center of the windings, the inductance increases if the core is a magnetic material. If the core is brass, the inductance decreases as the core moves to the center of the windings. A number of variable inductors are see in figure 3.

Variable inductors. Variable inductor products are coil products that allow the inductance to be easily varied by changing the position of the ferrite core in a threaded structure. The interior is covered by a metal case that is magnetically shielded, while a resin molded structure protects the windings with a high degree of reliability. Variable inductors.

INSTRUCTIONS. Wrap hundreds of turns of magnet wire around the paper tube. Connect this home-made inductor in series with an AC power supply and lamp to form a circuit. When the tube is empty, the lamp should glow brightly. When the steel bar is inserted in the tube, the lamp dims from increased inductance (L) and consequently increased ...

Variable capacitors are required for tuned LC oscillators. The capacitance can be varied by adjusting A, d orE in the earlier equation. Variable area types use an air dielectric and two vane sets whose relative angular position can be adjusted. Trimmer capacitors often vary separation d of sprung plates.
