Abstract
The utility model discloses an electromagnet principle tester, which comprises a base plate. A battery, a coiling frame, an iron core, an enameled wire and a lead are arranged on the base plate. The enameled wire is wound on the coiling frame. The positive pole and the negative pole of the battery are respectively connected with the two ends of the enameled wire through the lead. The iron core is inserted inside the coiling frame. A compass is arranged on one end of the coiling frame and the iron core. The electromagnet principle tester which has the advantages of simple structure, easy operation and high safety fully improves operational abilities of students and significantly boosts the enthusiasm of students for studying natural science. Thus, good effects are achieved.
Description
Technical field
The utility model relates to a kind of education experiment equipment, relates in particular to a kind of electromagnet experiment device for principle.
Background technology
In the middle of the study of compulsory education course school science science, the teacher is in explanation electromagnet principle, particularly the magnetic size of electromagnet and polarity and what have when relation, the teacher still only is that explanation is theoretical mostly, students is listened to such an extent that be confused, without enough understanding, this do not have the uninteresting teaching of experimental apparatus can not play good teaching function.
The utility model content
The utility model provides a kind of electromagnet experiment device for principle that cooperates theory teaching in order to solve weak point of the prior art.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: the electromagnet experiment device for principle, comprise base plate, base plate is provided with battery, bobbin, iron core, enameled wire and wire, enameled wire is wrapped on the bobbin, the both positive and negative polarity of battery is connected with two terminations of enameled wire by wire respectively, and iron core is plugged in the bobbin.
One end place of described bobbin and iron core is provided with a compass.
Described bobbin one end is provided with disk, and an end of iron core is provided with the baffle plate greater than the bobbin internal diameter, the other end of the iron core clamp nut that has been threaded, and clamp nut is by backing plate and disk immovable fitting.
Adopt technique scheme, when experiment, prepare some clips in advance, by whether plugging these variations of iron core in the quantity of changing battery, the number of turn that is wrapped in enameled wire on the bobbin, the bobbin, the quantity that picks up clip according to bobbin judges that what the magnetic size of electromagnet have relation with, and the both positive and negative polarity by the exchange battery, respectively compass is inhaled mutually or repelled each other to judge electromagnet polarity.
The utility model is simple in structure, easy operating, high safety, fully improves student's manipulative ability, and greatly improves the natural science applied enthusiasm of Students ' Learning, plays the good result of getting twice the result with half the effort.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, electromagnet experiment device for principle of the present utility model, comprise base plate 1, base plate 1 is provided with battery 2, bobbin 3, iron core 4, enameled wire 5 and wire 6, enameled wire 5 is wrapped on the bobbin 3, the both positive and negative polarity of battery 2 is connected with two terminations of enameled wire 5 by wire 6 respectively, and iron core 4 is plugged in the bobbin 3.One end place of bobbin 3 and iron core 4 is provided with a compass 7.Bobbin 3 one ends are provided with disk 8, and an end of iron core 4 is provided with the baffle plate 9 greater than bobbin 3 internal diameters, the other end of iron core 4 clamp nut 10 that has been threaded, and clamp nut 10 is by backing plate 11 and disk 8 immovable fitting.Battery 2 can adopt dry cell.
When experiment, can allow the student first with above-mentioned assembling parts, and prepare several clips in advance.By whether plugging iron core 4 these variations in the quantity of changing battery 2, the number of turn that is wrapped in enameled wire 5 on the bobbin 3, the bobbin 3, the quantity that picks up clip according to bobbin 3 surfaces judges that what the magnetic size of electromagnet have relation with, and by exchanging the both positive and negative polarity of battery 2, compass 7 is inhaled mutually still repelled each other to judge electromagnet polarity respectively.
