Abstract

An apparatus for generating a parallel magnetic field by passing current through a coil cylindrically wound and shielded against the external magnetic fields by a magnetically shielded housing incorporating a fine meshed material such as a high magnetic permeability amorphous alloy. Inside the housing, there are provided a non-magnetic bobbin, on which the coil is wound, and a power source for providing current to the coil to produce a parallel magnetic field of an intensity corresponding to that of the current to be generated within the bobbin.
