Abstract
The utility model discloses a novel demonstration device used for demonstrating a relation between magnetic force and distance. The demonstration device comprises a pedestal. A fixed plate and a sliding groove are disposed on the pedestal. A spring is fixedly connected with the fixed plate and is connected with a metal sheet. A magnet is disposed on the sliding groove and slides along the sliding groove. When the magnet is close to the metal sheet, the metal sheet draws close to the magnet in order to pull the spring to generate deformation. When the magnet is far from the metal sheet, the magnetic force is decreased and the metal sheet does not affected by the magnet. And thus the spring is reset. The demonstration device is capable of vividly and visually making students understand a physical phenomenon that the magnetic force is decreased gradually as the distance is increased and making physics teaching no longer abstract.
Description
Technical field
The utility model relates to the physical teaching aid field, is a kind of magnetic force and distance relation demonstration device specifically.
Background technology
At present, in physics teaching, being subjected to the distance recent photo to ring teaching of this knowledge for the magnetic force size, is all generally that the teacher gives an oral account to the student, allows the student firmly remember its variation relation, is not easy to student's understanding and grasps this knowledge point.
The utility model content
Technical assignment of the present utility model is for above-mentioned technical deficiency, and a kind of novel magnetic and distance relation demonstration device are provided.
The technical scheme that the utility model technical solution problem adopts is: novel magnetic and distance relation demonstration device, comprise base, described base is provided with fixed head and sliding tray, be fixedly connected with spring on described fixed head, described spring is connected with iron plate, described sliding tray is provided with magnet, and this magnet slides along sliding tray.
The beneficial effect that the utility model can bring is: the student that allows that can be vivid understands the physical phenomenon that magnetic force reduces gradually along with the distance increase, allows physics teaching become no longer abstract.
Description of drawings
Fig. 1, the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is done following detailed description:
As shown in Figure 1, the utility model discloses a kind of novel magnetic and distance relation demonstration device, comprise base 1, described base 1 is provided with fixed head 2 and sliding tray 6, be fixedly connected with spring 3 on described fixed head 2, described spring 3 is connected with iron plate 4, described sliding tray 6 is provided with magnet 5, and this magnet 5 slides along sliding tray 6, when magnet 5 is near apart from iron plate 4, iron plate 4 can be drawn close to magnet 5, pull spring 3 that deformation occurs, when magnet 5 was far away apart from iron plate 4, magnetic force diminished, iron plate 4 can not be subject to magnet 5 impacts, and spring 3 resets.The student that allows that the utility model energy is vivid understands the physical phenomenon that magnetic force reduces gradually along with the distance increase, allows physics teaching become no longer abstract.
