ABSTRACT:
A magnetizing system includes a transformer core, a first winding surrounding the core and a tube-like second winding surrounding the first winding. The second winding is formed with a slot on its upper surface and has a portion located within this slot and extending beyond the upper surface of said tube. This portion is formed with a cross-section of a size substantially smaller than the size of the slot to produce a magnetic field of high density. A screening socket is positioned adjacent the material to be magnetized. This socket is made of a material having good electrical conductivity for absorbing the stray fields so that the material to be magnetized is exposed to the magnetic field produced by said extended portion.
