This Design Idea shows how tocalculate the inductance of amultilayer air-core coil using only itsdimensions and resistance. If you knowthe dimensions and the number of turnson an air-core coil, you ...

In attempting to improve the efficiency of wireless power transfer it is essential to consider the losses associated with the proximity effects of the transmit and receive coils. Optimizing the link ...

While at the Hacker Hotel camp in the Netherlands back in February, our attention was diverted to an unusual project. [Niklas Fauth] had bought along a Tesla coil, but it was no ordinary Tesla coil.

High frequency Helmholtz coils are often used to generate uniform but time varying high frequency magnetic fields for a number of applications such as magnetic field susceptibility, calibration, and ...
