On June 22, 2011, scientists at Helmholtz-Zentrum Dresden-Rossendorf set a new world record for magnetic fields with 91.4 teslas. To reach this record, the researchers developed a coil weighing about ...

THE use of two equal and co-axial circular coils of wire, separated by a distance equal to their common radius and traversed by the same electric current in the same sense, has long been the standard ...

This Design Idea presents a differential safety device to prevent risks arising from current leakages in household applications. The proposed circuit uses a new method for differential current sensing ...
