Abstract
In our experiments of magnetic microscope and magnetic particle detection using an anisotropic magnetoresistive (AMR) sensor, we found that any nonmagnetic materials can also produce signals when they were close to the AMR senor. By simultaneously monitoring the temperature and the output signal of AMR sensor, we proved that these signals were caused by the thermal disturbance induces by the noncontact specimens.
