Abstract
The utility model discloses a kind of Multifunctional electroscope, comprise base, described base is provided with a vertical rod, the top of described vertical rod is vertically connected with a cross bar, described base is arranged a facade, described facade is provided with a core scale, and described core scale center is connected a pointer with cross bar by fishing line, and described cross bar connects a prill by thin cotton thread.Described pointer center arranges an aperture, and described pointer is fixed on fishing line.The utility model structure is simple, and easy to use, the utility model is in order to solve the problem of conventional electroscope function singleness, whether the utility model can check object with electric charge, object institute can be checked electrically charged, also can demonstrate the phenomenon of electric charge interphase interaction rule, functional diversities.
Description
Technical field
The utility model relates to a kind of Multifunctional electroscope.
Background technology
Whether the electroscope function singleness used in middle school physical experiment room, can only check object with electric charge, and can not check which kind of electric charge of object band, can not demonstrate the phenomenon of electric charge interphase interaction rule.The application to wish by pointer and bead, in the interaction of electrified body, to realize the function more than conventional electroscope.
Summary of the invention
The utility model provides a kind of Multifunctional electroscope for the defect of prior art.
The utility model is for realizing above object, adopt following scheme: a kind of Multifunctional electroscope, comprise base, it is characterized in that, described base is provided with a vertical rod, the top of described vertical rod is vertically connected with a cross bar, described base is arranged a facade, described facade is provided with a core scale, and described core scale center is connected a pointer with vertical rod by fishing line, and described cross bar connects a prill by thin cotton thread.
Preferably, it is characterized in that, described pointer center is installed with fishing line.
The beneficial effects of the utility model: the utility model structure is simple, easy to use, make full use of the interaction between electrified body and pointer, prill, solve the problem of conventional electroscope function singleness, object can be checked whether with electric charge, object institute can be checked electrically charged, also can demonstrate the phenomenon of electric charge interphase interaction rule.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
A kind of Multifunctional electroscope as illustrated in the drawing, comprise base 1, described base 1 is provided with a vertical rod 2, the top of described vertical rod 2 is vertically connected with a cross bar 3, described base) on a facade 4 is set, described facade 4 is provided with a core scale 5, and described core scale 5 center is connected a pointer 7 with vertical rod 2 by fishing line, and described cross bar 3 connects a prill 6 by thin cotton thread.Described pointer 7 center is installed with fishing line.
Embodiment, adjusts base 1, vertical rod 2, cross bar 3, facade 4, and whether demonstration inspection object is with Electricity Functional, the pointer 7 not charged with rubbed object close (not contacting) or small metal ball 6, pointer 7 rotates or small metal ball 6 moves, then object is charged, otherwise not charged.Core scale 5 is for observing the situation of the stressed skew of pointer 7.
The electrical functionality of the unknown electrified body of demonstration and verification, the rubber bar rubbed with fur contacts with pointer 7, and allow the negative charge on rubber bar transfer on pointer 7, now pointer 7 has just brought negative charge; With the electrical electrified body of the unknown near pointer 7, as electrified body and pointer attract each other, then what electrified body was charged is electrically positive electricity, otherwise is negative electricity.
Interaction rule function between demonstration electric charge, the rubber bar rubbed with fur and pointer 7 is tactile, and allow the negative charge on rubber bar transfer to pointer 7, now pointer 7 brings negative charge; With the rubbed rubber bar of fur near pointer 7, like charges repels mutually; With the rubbed glass bar of silk near pointer 7, xenogenesis electric charge attracts each other.
Claims (2)
