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 ...

As a fledgling electronics buff I gathered together the usual hodgepodge of spare parts, old TV's and all the other electrical odds and ends that youngsters bitten by that particular bug seems to ...

In the race for ever-improving technology, there are two related technical capabilities that drive our world forward: speed and size. These are related, as the smaller a device is, the less distance ...

Mobile-phone chargers and other devices could become much smaller after an all-RIKEN team of physicists successfully shrunk an electrical component known as an inductor to microscale dimensions using ...

A basic building block of modern technology, inductors are everywhere: cellphones, laptops, radios, televisions, cars. And surprisingly, they are essentially the same today as in 1831, when they were ...

Inductors are not the most common component these days and variable ones seem even less common. However, with a ferrite rod and some 3D printing, [drjaynes] shows how to make your own variable ...

For decades, power-supply designers have set their inductor ripple current to somewhere between 20% and 40% of their power supply’s full rated output current. This is considered a good starting point ...

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 ...
