Magnetic sensor and magnetic field sensing method using said magnetic sensor based on impedance changes of a high frequency excited conductor |
摘要 |
In a magnetic field sensing method in accordance with the invention of the present application, a magnetic sensor comprising a conductor and at least one magnetic material provided on any of the surfaces of this conductor, is employed. This magnetic sensor is disposed in the vicinity of an external magnetic field which is to be sensed, and by means of supplying a high frequency current to this conductor, the impedance of the conductor changes in accordance with the external magnetic field, and based on this, the external magnetic field is sensed.
