What is an inductor coil?

Coils are typically what people are referring to when they talk about an inductor. As you already learned, it is just a coil of wire carefully tuned to maintain a magnetic field of a particular strength. These are ubiquitous within electronics, particularly when dealing with wireless devices.

How is inductance measured in a coil?

Different coils have different amounts of inductance. This is measured in Henries. Typically, most inductors are measured in the uH (microhenry) range. You may see an inductor represented in a schematic as a series of squiggly loops or, if there is a core, as a bunch of squiggly loops cozying up to two parallel lines.

What are specialized inductors?

However, speakers, motors, electromagnets, reed relays, and transformers are all basically specialized inductors. While you may not often find yourself winding and tuning coils, inductors hardly went away, and it is still important to have a loose grasp on these concepts. An inductor is basically a coil of wire. That's it.

Do inductors have a solid core?

Inductors without a solid core are considered to have an "air core." This offers considerably less inductance. Instead of diving deep into how inductors work, let's discuss common inductors you may encounter when starting with electronics, and what you might use them for.

Do radio amateurs love inductors?

Radio amateurs often have a love-hate relationship with home-made inductors, sharing all kinds of tips and tricks as to how the most stable nanohenry inductor can be wound. But there’s another group in the world of electronics with an interest in high-quality inductors, namely the audio enthusiasts.

What kind of inductors do you need for a loudspeaker crossover?

They need good quality inductors with a values in the millihenries, to use in loudspeaker crossover networks. [Homemade Audio] takes us through their manufacturing process for these coils, and the result is a watchable video resulting in some very well-made components.
