A magnetic stimulation probe is provided to produce a probe electromagnetic field within a patient. The magnetic stimulation probe has a first generally planar magnetic field generating coil having a first coil trace having a decreasing radial spiral which passes about a first central portion, the first coil trace having a first electric current traveling in a first direction and having a first plurality of separated portions each having a first respective set of different radii from the first central portion along a bisecting line. The first planar coil has a second coil trace having a second electric current traveling in a second direction which is parallel to the first direction, and having a second plurality of separated portions each having a second respective set of different radii from the first central portion along the bisecting line along the bisecting line. Two such coils can be arranged to produce a high intensity focused magnetic field at a distance from the probe. The probe electromagnetic field is operable to induce a current in a conductive material.
