Abstract

The present invention provides a method and apparatus for delivering an electric field to a body by delivering a first magnetic field from a first coil in a first orientation to a body and directed at a desired target within the body, and delivering a second magnetic field from a second coil in a second orientation directed at the desired target within the body to induce an electric field across the desired target, wherein only one magnetic field is delivered to the body at any one time.
