Resumo

Presently-used magnetic stimulators use multiturn round coils. The self-inductance of the coil increases with the square of the number of turns in the coil The self-inductance can be reduced without any loss in focalization by a coil that is shaped as a half toroid ("Slinky"). A computational technique was developed to model this configuration and to predict the magnetic field and current densities in the resistive tissues of the brain.
