Abstract
The utility model relates to a technology of a demonstration device of electricity of physics. The demonstration device for ampere force and electrostatic force comprises a panel, a conductive column fixed on the panel, a groove arranged on the conductive column, and a conducting wire movably arranged on the groove. The demonstrator can obviously observe mutual attraction or repulsion between the wires by applying extremely small current, and demonstrate ampere force, electrostatic force and left-hand rule.
Description
The utility model belongs to the technical field of the apparatus for demonstrating of physical electricity.
In the high school physics class between the electric current interactional experiment be difficult to succeed, reason is that demonstration device is to be fixed with two leads that are parallel to each other on a panel, two leads interact when passing to electric current, but two leads resistance when interacting is too big, both made and passed to very big electric current, interactional effect is also not obvious, and the student is difficult to observe interactional phenomenon.
The purpose of this utility model provides and a kind ofly passes to very little electric current and both can significantly observe interactional Amp and electrostatic force demonstration device.
This Amp and electrostatic force demonstration device comprise panel, are fixed on the conductive pole on the panel, are provided with groove on conductive pole, and lead is equipped with in activity on groove.
Because two leads are equipped with in activity on the drum shape groove of 4 conductive poles, frictional resistance between lead and conductive pole is very little, thereby as long as in two leads, pass to very little in the same way or inverse current, two leads are attracted each other or repel, make the significantly close or separation of two leads, clearly demonstrate out the existence of Amp, cooperate repulsion and the attraction that to demonstrate out static with induction machine.And cooperate horsehoe magnet can demonstrate the left-hand rule experiment.
Accompanying drawing shows embodiment of the present utility model, wherein:
Figure 1 shows that the front elevation of Amp and electrostatic force demonstration device;
Figure 2 shows that the right view of Amp and electrostatic force demonstration device;
Enlarged drawing cuts open in the office that Figure 3 shows that conductive pole 2.
Amp as shown in the figure, electrostatic force demonstration device, comprise panel 1, correspondence is contained in four conductive poles 2 on the panel 1 in pairs, be located at the groove 3 on the conductive pole 2, groove 3 is drum shape, is marked with mercury 5 in groove 3, lead 4 is equipped with in activity on the groove 3 of every pair of conductive pole 2, be welded with prong 6 at the two ends of lead 4, lead 4 is to be inserted in the groove 3 interior activities that are marked with mercury 5 by prong 6 to be contained on the conductive pole 2, and two leads 4 are parallel.
In use, in two leads, pass to the electric current of equidirectional by conductive pole, then two parallel wires attract each other and draw close, pass to the opposite electric current of direction as two leads, then two parallel wires repel mutually, away from, thereby can demonstrate out the existence of Amp, and used electric current is very little, both can realizes with two joint No.5 cells.If cooperate induction machine can demonstrate the repulsion and the attraction experiment of static, cooperate horsehoe magnet can demonstrate the left-hand rule experiment.
