A magnetic field sensor comprises a power source, an indicator and a microprocessor. The power source supplies current to the indicator. The indicator turns on when a magnetic field is sensed and the indicator turns off when a magnetic field is not sensed. The microprocessor renders the indicator inoperable a predetermined period of time after the magnetic field sensor is powered up.
