A perspex sheet is a square plate, an RbFeB strong magnet is fixed and installed in parallel on the perspex sheet to form a magnetic field area, two brackets vertical to the perspex sheet are fixed on the central axis of the parallel RbFeB strong magnet and are connected with each other through an insulated cross beam, a flexibility ergometer is arranged on the insulated cross beam, and an insulated wire is hung on an electronic scale hook of the flexibility ergometer. A rechargeable supercapacitor is further fixed on the perspex sheet, one electrode of the supercapacitor is sequentially connected with a switch and a conductive hook at one end of the insulated wire through a wire, the other electrode of the supercapacitor is connected with a conductive hook at the other end of the insulated wire through a wire, and the two conductive hooks are provided with a copper tube. Compared with the prior art, the ampere force quantitative measurement instrument is easy to manufacture, the size of the ampere force can be shown by changing the inclination angle of the hanging copper tube, so that the size of the ampere force is verified, the interest of a student is motivated, and the ampere force quantitative measurement instrument is an easily transformed physical experiment device.
Description
Technical field
The utility model relates to a kind of Physical Experiment modifying device, is Ampère force quantitative measurment instrument specifically.
Background technology
In physics teaching, Ampère force is an important knowledge point of high school physics, is also a focus of college entrance examination in recent years.In the new teaching of Ampère force size, the past, often the teacher by experiment can only its size of qualitative examination, can only semiquantitatively study at most, probed into not thorough.The size of how accurately to probe into Ampère force is a difficult point in teaching always, is perplexing the Middle School Physics teacher.Also do not have at present teaching aid preferably quantitatively to demonstrate the size of Ampère force.
The utility model content
For the problem in background technology, the utility model provides a kind of Ampère force quantitative measurment instrument.
the utility model is for solving above technical matters, adopt following technical scheme: Ampère force quantitative measurment instrument, by poly (methyl methacrylate) plate, ultracapacitor, rubidium iron boron strong magnet, wire, switch, copper pipe, conductive hook, the insulation crossbeam, support, sensitive dynamometer, electronic scale hook and insulated wire form, poly (methyl methacrylate) plate is square plate, above the parallel rubidium iron boron strong magnet that is mounted with form field regions, on the axis of parallel rubidium iron boron strong magnet, be fixed with two supports perpendicular to poly (methyl methacrylate) plate, support connects by the insulation crossbeam, above the insulation crossbeam, a sensitive dynamometer is arranged, the electronic scale hook of sensitive dynamometer is hanging insulated wire.
As preferably, above poly (methyl methacrylate) plate, also fix a chargeable ultracapacitor, ultracapacitor one utmost point is by the wire conductive hook of connecting valve and insulated wire one end in turn; Another utmost point is connecting the conductive hook of the insulated wire other end by wire; Two are placed with copper pipe above conductive hook.
Further, copper pipe has a round towards a side of conductive hook, and the hole correspondence the projection above conductive hook.
Compared with prior art, the utility model is made easily, by change, hangs the angle of inclination of copper pipe and can show the size of Ampère force, thereby verified the size of Ampère force, has excited student's interest, is a kind of physics facility that is easy to transform.

Wherein, 1. poly (methyl methacrylate) plate, 2. ultracapacitor, 3. rubidium iron boron strong magnet, 4. wire, 5. switch, 6. copper pipe, 7. conductive hook, 8. insulation crossbeam, 9. support, 10. sensitive dynamometer, 11. electronic scales hooks, 12. insulated wires.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is done in further detail and is introduced:
Ampère force quantitative measurment instrument, by poly (methyl methacrylate) plate 1, ultracapacitor 2, rubidium iron boron strong magnet 3, wire 4, switch 5, copper pipe 6, conductive hook 7, insulation crossbeam 8, support 9, sensitive dynamometer 10, electronic scale hook 11 and insulated wire 12 form, poly (methyl methacrylate) plate 1 is square plate, above the parallel rubidium iron boron strong magnet 3 of being mounted with form field regions, on the axis of parallel rubidium iron boron strong magnet 3, be fixed with two supports 9 perpendicular to poly (methyl methacrylate) plate 1, support 9 connects by insulation crossbeam 8, above insulation crossbeam 8, a sensitive dynamometer 10 is arranged, the electronic scale hook 11 of sensitive dynamometer 10 is hanging insulated wire 12.Above poly (methyl methacrylate) plate 1, also fix a chargeable ultracapacitor 2, ultracapacitor 2 one utmost points are by wire 4 conductive hook 7 of connecting valve 5 and insulated wire 12 1 ends in turn; Another utmost point is connecting the conductive hook 7 of insulated wire 12 other ends by wire 4; Above two conductive hook 7, be placed with copper pipe 6.Copper pipe 6 has a round towards a side of conductive hook 7, and the hole correspondence the projection above conductive hook 7, is conducive to like this keep the distance of copper pipe 6 between two conductive hook 7.
During use, first give ultracapacitor 2 chargings, by figure, connect device, turn on-switch 5, the reading that can observe sensitive dynamometer 10 changes, change insulated wire 12 and link up with 11 contact point with electronic scale, make copper pipe 6 and magnetic field have a certain degree, can verify the relation of Ampère force and angle; Change the quantity of rubidium iron boron strong magnet 3 and then the intensity in change magnetic field, can verify the impact of magnetic field on Ampère force; Having excited student's interest, is a kind of physics facility that is easy to transform.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
