Abstract: PURPOSE: A method and apparatus for improving uniformity of magnetic field of solenoid using single current source is provided to achieve an improved performance of the sensor or valve using the solenoid by improving uniformity of magnetic field in the internal center of the solenoid. CONSTITUTION: A current(I0) is applied to a circuit having a main solenoid resistance(Rms) by using a single current source, in such a manner that a number of different currents are produced by a single power supply device and a shunt resistance(Rm) and supplied to a multi-layer solenoid. The shunt resistance is arranged in front of the main solenoid resistance. An optimum condition for obtaining the maximum uniformly around the center point of the interior of the solenoid, is obtained by Legendre polynomial. Subsequently, circuits consisting of auxiliary current adjustment resistances(R1m,R2m) and auxiliary solenoids(R1s,R2s), respectively, are arranged at both ends of the shunt resistance. Thus, a plurality of solenoids are superposed, and currents(I1,I2) being applied to each solenoids are distributed differently, so as to expand the uniform magnetic field space.

Abstract: PURPOSE: An external magnetism offsetting apparatus is provided to offset external magnetism since current for offsetting external magnetism is applied to an external magnetism offsetting coil. CONSTITUTION: A reference frequency generator(210) generates reference frequency signals. The external magnetism offsetting coil(220) has the inner diameter greater than the inner diameter of a magnetic field generating coil(120). The external magnetism offsetting coil is arranged in the shape of a concentric having the same central axis with a magnetic field generating coil. A magnetic field sensor(230) senses the magnetic field created from the magnetic field generating coil. A resonant frequency generator(240) creates resonant frequency signals compared with the magnetic field detected through the magnetic field sensor. A phase comparator(250) creates the current for offsetting the external magnetism. A current amplifier(260) amplifies the current of the phase comparator.
