    Abstract: A method for gapping a ferrite core (10) by coating the core with a stabilizing material (32), fracturing the core with a laser beam (44) thereby creating one or more gaps (47) in the cores magnetic field, optionally opening the fracture to obtain a desired inductance, and then sealing the core.
