Abstract
The utility model relates to a magnetic electrical component used for teaching demonstration. The magnetic electrical component consists of a substrate and electrical elements fixed on the front surface of the substrate. The magnetic electrical component is characterized in that one or more than one magnet is inlaid on the bottom of the substrate; the electrical elements comprise large electrical elements such as a slide rheostat and a demonstration ammeter; and a plurality of magnets are embedded on the substrate below the large electrical elements. The magnetic electrical component used for teaching demonstration is advantageous in that the strong magnets are fixed at the bottom portions of a constant value resistor, a switch, a battery, a light bulb, the slide rheostat, the demonstration ammeter and other electrical elements, such that the electrical elements can be attached on a magnetic blackboard, as a result, a large circuit formed through the connection of the electrical elements can be formed on the blackboard, and circuit diagrams, operation processes, experimental phenomena and the like are clearly visible to a whole class; thus, the magnetic electrical component can be beneficial to the improvement of learning interests, especially be beneficial to the step-by-step explanation of experiment processes; and the magnetic electrical component is of easiness in teaching for a teacher and in understanding for students as well as great popularization value.
Description
Technical field
The utility model relates to a kind of physical teaching aid, particularly teaching demonstration magnetic electricity component.
Background technology
Existing Experiments of Electricity, substantially be each equipment to be placed on desktop (or establishing slightly high platform at desktop) test, Most students does not observe the process of experiment in the class, some schools is each electric elements to be plugged on homemade erect plate test, be the inconvenience of avoiding carrying and collecting, erect plate can not done very greatly, and visibility is still inadequate, Students ' Learning is still very difficult, and electricity is the heavy difficult point content of junior physics maximum always.
The utility model content
The purpose of this utility model is: for addressing the above problem, but provide a kind of magnetic to be attached to the magnetic electricity component for teaching demonstration on magnet board, the teacher can test on blackboard, to improve to greatest extent visibility, helps the student to understand and analyzes the electricity rule.
The technical scheme that the utility model adopts is: a kind of teaching demonstration magnetic electricity component, consisted of by substrate and the electricity component that is fixed on substrate front side, and it is characterized in that: the bottom of described substrate also is inlaid with one or more magnet.
Described electricity component comprises slide rheostat, demonstration ammeter, and described magnet has a plurality of.
The beneficial effects of the utility model are: the bottom of the electricity components such as fixed value resistance, switch, battery, bulb, slide rheostat, demonstration ammeter is fixed with kicker magnet, can be adsorbed on magnet board, can connect into very large circuit on blackboard, circuit diagram, operating process, experimental phenomena etc. be all the full class in visual and clear ground as seen, be beneficial to the raising learning interest, be beneficial to especially the explanation step by step to experimentation, teacher easily teaches, the student is understandable, has larger promotional value.
Description of drawings
Fig. 1 is structural representation of the present utility model;
In figure: 1 substrate, 2 magnets, 3 electricity components, 4 demonstration ammeters, 5 slide rheostats, 6 bulbs, 7 batteries, 8 switches, 9 fixed value resistances.
Embodiment
As shown in Figure 1, the front of substrate 1 is fixed with the electricity components such as fixed value resistance 9, switch 8, battery 7, bulb 6, slide rheostat 5, demonstration ammeter 4.The bottom of substrate 1 is inlaid with one or more magnet 2.Especially, to large-scale electricity components such as slide rheostat 5, demonstration ammeters 4, should be inlaid with a plurality of magnets 2 below it on substrate.
For ease of being adsorbed on blackboard, battery 7 can be selected battery of mobile phone.
Claims (2)
1. a teaching demonstration magnetic electricity component, be made of substrate and the electricity component that is fixed on substrate front side, and it is characterized in that: the bottom of described substrate also is inlaid with one or more magnet.
2. teaching demonstration as claimed in claim 1 magnetic electricity component, it is characterized in that: described electricity component comprises slide rheostat, demonstration ammeter, described magnet has a plurality of.
