Abstract:
1. A test method of testing characteristics of a magnetic sensor that has a magnetic-field sensing section that generates an output according to a magnetic force and magnetic-sensor terminals that sense remotely the output generated by the magnetic-field sensing section, the test method comprising: moving the magnetic sensor relative to a probe pin on a base to contact the probe pin and the magnetic sensor terminals to sense an output generated by the magnetic sensor; applying a magnetic force to the magnetic-field sensing section by an electromagnet being supported by the base, when the probe pin contacts the magnetic-sensor terminals; and moving the electromagnet with regard to the base by moving the magnetic sensor to cause the probe pin to contact the magnetic-sensor terminals, in a case where it is determined that the probe pin does not contact the magnetic sensor terminals as the electromagnet contacts the magnetic sensor.
