Abstract

PURPOSE:To obtain a magnetic sensor of high resolution by mounting magnetic material pieces of magnetized ferromagnetic materials or the like on the side face of a permanent, and securing reluctance elements to the surfaces of the magnetic poles. CONSTITUTION:A permanent magnet 1 assuming one side of the magnetic pole surface 2 of said magnet 1 of a rectangular parallelepiped defined as X axis, one side perpendicular to this as Y axis, and the other side perpendicular to these as Z axis, and reluctance effect elements 3, 4 are arrayed and fixed on the surface 2 in parallel with the Y axis. Here, the magnetic information to be read approaches and passes in a manner as to cross the elements 3, 4 successively from the X-axis direction of an arrow 5. Permalloy pieces 6, 7 of the shape which is slightly longer than the magnet 1 and is roughlyl the same in the width in the Y axis direction are affixed on the Y-Z axis plane having the sides parallel with the Y axis of the magnet 1. Then, the magnetic flux from the surface 2 emits into a space magnetic path, then it passes the inside of the permalloys, again emits into the space magnetic path and returns to the opposite poles. Hence, the elements 3, 4 are equally magnetically biased and the operating point is determined in the position where the change of square characteristics is large.
