Anything related to inductors.

Inductors are passive electrical components that exploit the properties of magnetic fields created by electrical currents circulating in conductors.

The most common type is a 2-terminal device. However a system of coupled inductors, like a transformer, can be packaged as a single component and can have many more terminals, depending on how many windings are present.

A common example of inductor is a coil of wire with its turn insulated from each other.

Q&A Can I make an AC inductor (reactor) rated 75mH 40A from a 3-phase induction motor?

For my test bench I need an inductor (aka "reactor") that meets the requirements below. I have tried to purchase it outright as a made-up item, or the parts to make it (core and windings), but have...

Q&A Capacitance gain using conductive core for inductors [closed]

I have learnt that if we have 2 parallel conductive plates and we seperate them the capacitance is increased if we put a good conductor between the plates. Now the resonant frequency of a inductor...
