It seems crazy,” Princeton physicist Chris Chyba remarked, reflecting on the device that now sits at the center of a debate ...

The device appeared to violate the conclusion that any conductor at rest with respect to Earth’s surface cannot generate power from its magnetic field,” Princeton’s Christopher Chyba added in a press ...

Ferrite beads (L1 in the photo) filter high frequency power supply noise by converting it into a tiny amount of heat. Power supply noise can cause various problems for many parts, especially in ...

At present, portable receivers generally use ferrite rod antennas for LF and MF (below 2 MHz), and whip antennas for HF (up to 30 MHz). Each type has proved effective in its particular application.

One of the best tools in the engineer’s lightning protection toolbox is a tried, true and frequently underutilized friend, the ferrite toroid. The principle is quite simple. If you have two (or more) ...
