Back to the basics: there are three kinds of passive electronic components: Inductors, Capacitors and Resistors. An inductor can be easily built and many types of core and bobbin kits are available.

You can make all sorts of different types of inductors, but the most common type is cylindrical coil of wire---a solenoid. When current runs through the first loop, it creates a magnetic field that ...

The fidget spinner posts will continue until morale improves. This time, we’re looking at [TannerTech]’s electromagnetic accelerator for a fidget spinner. [Tanner] can spin his fidget spinner ...

We report a fabrication technology for 3D air-core inductors for small footprint and very-high-frequency power conversions. Our process is scalable and highly generic for fabricating inductors with a ...

Excessive use of electricity and poor efficiencies are no longer acceptable. Eliminating poor power factor will result in increasing electrical efficiencies and will reduce the overall use of ...

Could the inductor be redesigned in a fundamentally new way? Yes, according to new work by researchers in the US, Japan and China who have made the first high-performance inductors from intercalated ...

Inductors have the exact opposite characteristics of capacitors. Inductors store energy in a magnetic field (produced by the current through wire), whereas capacitors store energy in an electric field ...

Inductors of all types — whether discrete, chip, bead or coil — are trying to keep pace with the demands of modern power-supply designs by using diverse forms and materials, such as thin films, ...
