An advanced metal detector coil encompasses the diameter of the sensor head. Passing current through the MD coil creates an electromagnetic field that induces an electrical current in any metal ...

At the time of writing there is still just about enough time to create a Hacky Racer for Electromagnetic Field. Following the example set from Germany, it’s possible that the hoverboard route ...

Toroidal vortices, common in fluid dynamics, are newly explored in electromagnetism as two distinct forms: vector toroidal pulses and scalar phase vortices. This work proposes hybrid electromagnetic ...
