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.

Over two centuries ago, physicist Michael Faraday described how electric current running through a coil of wire can create a magnetic field. This magnetic field can then induce an electric field ...

When you push the magnet through the middle of the coil, an electric current is produced ... as this helped to concentrate the magnetic field.

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 ...

Scientists have developed a single-cell green microalgae coated with magnetic material. This miniature robot was put to the test: would the microalgae with its magnetic coating be able to swim through ...

The world’s first superconducting planar coil magnet array successfully created and controlled stellarator-relevant magnetic field structuresThe ...

When you plug it in, the electric current passing through this coil generates a magnetic field. Meanwhile, phones that support wireless charging include a coil under their back plastic or glass ...
