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.

However, this invasive approach can damage brain tissue and lead to inflammation around the ... This coil, when activated, generates a precise magnetic field that stimulates specific brain regions.

This method requires the insertion of electrodes directly into the brain, which can cause damage to brain tissue, and in the long term, it can cause inflammation around ... magnetic field from ...
