Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
The utility model provides a kind of weak magnetic rapid measurement device, is mainly used in weak magnetic, the Quick Measurement of non-magnetic material and sorting.
This device comprises force measuring machine and magnetic field generation mechanisms.As shown in Figure 1, force measuring machine is balance 1, is positioned over the top of support 6, for measuring standard specimen and measuring stressed in gradient fields of sample, it comprises two specimen holders 2, and for placing the standard specimen of same physical dimension and measuring sample, sample and specimen holder are in the magnetic field measured and need; Magnetic field generation mechanisms comprise for realize magnetic field occur enamel covered wire 3, for increase magnetic field magnetic core 4 and for drive coil realize setting magnetic field direct supply 5, be positioned over the below of support 6; The symmetrical structure of described magnetic field generation mechanisms, two ends, left and right are respectively provided with a magnetic core 4; Enamel covered wire 3 is closely wrapped in outside magnetic core 4, and is connected with the direct supply 5 being arranged on mechanism centre position.
