Title:
MAGNETIC SENSOR AND CURRENT SENSOR PROVIDED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2018/008176
Kind Code:
A1
Abstract:
This current sensor is provided with: at least one permanent magnet (110); and at least one magnetosensitive body that detects, in a state wherein a bias magnetic field is being applied thereto from the permanent magnet (110), a magnetic field (2) to be measured. The permanent magnet (110) has a shape wherein the value of a permeance coefficient obtained by having, as the magnetization direction, the direction in which the magnetic field (2) is applied is 1.5 times the value of a permeance coefficient of the permanent magnet (110) in magnetization direction (1) of the permanent magnet or lower.
