Magnet be in slow charge and discharge process and magnetic does not disappear immediately, can so cause experiment error it is larger and it is repeated compared with
Difference；
C. process of the test：Close a switch, electromagnet, which is powered, possesses magnetic, at this moment by subjects（Iron or post
Piece or magnetic stripe）It is suspended on electromagnet；Switch is disconnected, electromagnet is powered off and magnetic disappears, subjects essence is metastable de-
From electromagnet；
D. attitude controller is changed：Change the experiment that different attitude controllers carry out other operating modes.
Compared with prior art, beneficial effect is：The characteristics of the utility model has flexible：It is adapted to different examinations
Condition, including the specific initial attitude of subjects, different initial adsorption power, different test heights are tested, or even is applied to
Especially irregular subjects of shape, then borrow the support of 3D printing technique, the controller unit that the utility model is provided can be with
Adapt to the Installation And Construction of all experiments；Secondly, the characteristics of controller unit that the utility model is provided has simple：The control
Instrument very simple in assembling, can very easily change attitude controller to meet different experiments during experiment
Operating mode；Again, the controller unit that the utility model is provided has high-precision feature：Due to electromagnet power-off in a flash its
Magnetic disappears, therefore subjects will not be disturbed by as cutting suspension collimation method from the external world in a flash in release, then
In addition the precision of 3D printing can reach 0.1mm, therefore whole controller unit can reach 0.1mm precision；Finally, this practicality
The controller unit of new offer has the characteristics of stablizing：Due to above-mentioned described various advantages, provided using the utility model
