1. A method for generating higher magnetic-field stimulation at a deep brain target than at more superficial cortical non-target brain regions, the method comprising the steps of: selecting a deep brain target, positioning an array of electromagnets about a patient's head, orienting the electromagnets so that components of magnetic-field energy from at least two of the electromagnets intersect at the deep brain target, wherein the deep brain target is deeper in the brain and further from the electromagnets than the more superficial cortical non-target brain regions; and simultaneously energizing at least two of the electromagnets, whereby a stimulating vector component of the magnetic field received at the deep brain target produces stimulation at the deep-brain target which is greater than that produced at the more superficial cortical brain locations between the deep brain target and the electromagnets.
