A coil configuration and method for transcranial magnetic stimulation enabling stimulation of deep regions of the brain without excessively stimulating the cortex is provided. The coil configuration utilizes at least one coil to produce an off-plane magnetic field to enhance the magnetic field from a top TMS coil. In one configuration three coils, referred to as the Triple Halo Coil and oriented at +30°, 0°, and −30° relative to the plane of the TMS coil, are used. In another configuration a single variable position coil referred to as the Variable Halo Coil and positionable vertically and/or angularly is used.
