Magnetic Field Detectors

Troubleshoot solenoid valves, check relays, and test permanent magnets by detecting if a magnetic field is present. Hold these detectors near a surface and they'll light up blue if they sense a magnetic field. They don't measure the strength or direction of the magnetic field.
