Title:
MAGNETIC SENSOR AND MAGNETIC SENSOR SYSTEM
Document Type and Number:
Japanese Patent JP2022101863
Kind Code:
A
Abstract:
To provide, among others, a magnetic sensor capable of detecting magnetism from frequency fluctuation of an AC current flowing through a magnetic sensitive element that makes use of the magnetic impedance effect.SOLUTION: A magnetic sensor 110 is provided, comprising: a frequency setting unit 10 consisting of a magnetic sensitive element unit 11 with a magnetic sensitive element 1 configured to sense a magnetic field by means of the magnetic impedance effect and a capacitive element unit 12 with a capacitive element 2 that are serially connected, the frequency setting unit being configured to set an oscillation frequency using the magnetic sensitive element unit 11 and the capacitive element unit 12; and an electrical potential supply unit 20 configured to supply electrical potential such that the AC current of a frequency set by the frequency setting unit 10 flows to the frequency setting unit 10.SELECTED DRAWING: Figure 1
