| Abstract: | With electrical products becoming miniaturized,it is more difficult to measure the magnetic field caused by permanent magnets in them.A method for measuring 3-D magnetic field of the permanent magnet with three single-dimension Hall probes was proposed.The designed system based on the method have many characteristics,such as real-time display,depicting magnetic flux density,high automation and sensitivity,diminution of the dead zone and so on.The system can be properly used to check the magnetic characteristics and magnetizing effect in engineering practice. |
