A coil of wire, or solenoid, consists of a wire coiled up into a spiral shape. When an electric current flows, the shape of the magnetic field is very similar to the field of a bar magnet.

This coil, when activated, generates a precise magnetic field that stimulates specific brain regions. “The magnetic field generated by the coil is approximately 500 milliTesla (mT), about 10 ...

Physicists and engineers have developed a groundbreaking method to measure magnetic field orientation using atoms as tiny ...

It uses a number of coils to produce a magnetic field to levitate the 3D printed plastic snail which contains the lighting element itself. The actively controlled levitation base uses a magnetic ...

The MPI system also incorporates a water-cooled 26.3 kHz drive coil, which produces the oscillating magnetic field (of up to 7 mT peak) needed to drive the SPIONs in and out of saturation. A ...

These papers detail the practical advantages of the planar coil stellarator as well as the methods used to design the planar (i.e. flat) magnetic coils, allowing for a commercial maintenance scheme.

Getting a magnetic field to balance on another magnetic field ... He pulled off this tricky project using a set of four coils he got off of Taobao (the Chinese version of eBay), a hall effect ...
