Description
DC magnetic fields can develop in many steel or iron objects if they have been exposed to magnetic fields, current, or friction. Even structural members in homes and barns have become magnetized due to stray voltage. This hand-held device detects residual magnetism in steel parts quickly and accurately. Simply place the test edge near or against the object being tested, and the needle gauge points to a reading representing the magnetism in the object at that site as well as polarity. Will also verify thoroughness of de-magnetizing. Check out your car, bed frame, desk furniture or any other metal objects you spend time with. Can also be used to check the strength of magnets. Two models in stock: -20 to +20 and -100 to +100 Gauss.Pocket Magnetometer magnetic field detector
