Description
Technical field
The present invention relates to a kind of popular science knowledge apparatus for demonstrating, specifically the apparatus for demonstrating of hand power.
Background technology
1, ninth grade physics (junior three) the 17 chapter second joint (P118, P119): generator has the magnet (stator) that can produce magnetic field, a coil that can rotate (rotor) in magnetic field.Shake handle, make the rotor quick rotation, miniature bulb is just bright.This shows that generator has sent.A part of conductor in the closed circuit produces electric current when doing the cutting magnetic induction line motion in magnetic field phenomenon is called electromagnetic induction phenomenon, and the electric current that produces in the electromagnetic induction claims induction current.
2, second physics of senior middle school (Senior Two) the 16 chapter the 3rd joint P200: induction current has such direction, and promptly faradic magnetic field hinders the variation that causes faradic magnetic flux always.Here it is Lenz law.
Summary of the invention
The purpose of this utility model is design a kind of popular science knowledge apparatus for demonstrating, the specifically apparatus for demonstrating of hand power.
Concrete structural design scheme is as follows:
The apparatus for demonstrating of hand power, on Demonstration table, be provided with coil, portion is provided with a permanent magnet in coil, the position vertical with permanent magnet in the Demonstration table side is provided with handwheel, handwheel links to each other with permanent magnet, the Demonstration table opposite side corresponding with handwheel is provided with vertical demonstration board, is provided with the direction of current pilot lamp on demonstration board, and coil and direction of current pilot lamp connect into the circuit that coincidence circuit is learned rule by lead.
Useful technique effect of the present utility model is embodied in following aspect:
The utility model both can be used for the science popularization venue, the science and technology center of flowing, and as the science popularization showpiece, also can be used for middle school physical curriculum, as a kind of aided education experiment product, can demonstrate hand power visual in imagely, was convenient to the understanding of student's intensification to the content of courses.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment:
The apparatus for demonstrating of hand power, structure comprises Demonstration table, on Demonstration table, be provided with coil 3 (see figure 1)s, be provided with a permanent magnet 2 in coil 3 inside, be provided with handwheel 4 in Demonstration table side and permanent magnet 2 vertical positions, handwheel 4 links to each other with permanent magnet 2, and the Demonstration table opposite side corresponding with handwheel 4 is provided with vertical demonstration board 5, be provided with direction of current pilot lamp 1 on demonstration board, coil 3 and direction of current pilot lamp 1 are connected into the circuit that meets the electricity rule by lead.
The utility model is reasonable in design, simple in structure, easy to operate, be suitable for teaching and science popularization demonstration: pass through swing handle, make magnet in the showpiece along the track move left and right, in coil, produce induction current, thereby it is relevant with the magnet moving direction to observe faradic direction, deepens the understanding to Lenz law.
