Abstract
The invention provides a magnetic electrical element used for teaching demonstration. The magnetic electrical element is composed of a substrate and electrical elements which are fixed on the front surface of the substrate. The magnetic electrical element is characterized in that one or more than one magnets are inlaid in the bottom part of the substrate. The electrical elements comprise a slide rheostat, a demonstration ammeter and other large electrical elements. Multiple magnets are inlaid in the substrate below the large electrical elements. The beneficial effects of the magnetic electrical element used for teaching demonstration are that the strong magnets are fixed at the bottom parts of a fixed value resistor, a switch, a battery, a bulb, the slide rheostat, the demonstration ammeter and other electrical elements so that the electrical elements can be adsorbed on a magnetic blackboard, an extremely large circuit can be formed on the blackboard through connection, the circuit diagrams, the operation process and experiment phenomena can be visually and clearly seen by the whole class, enhancement of learning interest is facilitated, step-by-step explanation of the experiment process is particularly facilitated, teaching is easy for teachers, students are easy to understand, and thus the magnetic electrical element used for teaching demonstration has relatively high popularization value.
Description
Technical field
The present invention relates to a kind of physical teaching aid, particularly teaching demonstration magnetic electricity component.
Background technology
Existing Experiments of Electricity, substantially be each equipment is placed on desktop (or establishing slightly high platform at desktop) test, Most students does not observe the process of experiment in the class, each electric elements are plugged on homemade erect plate to test by some schools, for avoiding the inconvenience of carrying and collecting, erect plate can not do very large, and visibility is still inadequate, Students ' Learning is still very difficult, and electricity is the maximum heavy difficult point content of junior physics always.
Summary of the invention
The object of the invention is: for solving the problem, provide a kind of and can be attached to the magnetic electricity component for teaching demonstration on magnet board by magnetic, teacher can test on blackboard, to improve visibility to greatest extent, helps student to understand and analyzes electricity rule.
The technical solution adopted in the present invention is: a kind of teaching demonstration magnetic electricity component, is made up of, it is characterized in that: the bottom of described substrate is also inlaid with one or more magnet substrate and the electricity component being fixed on substrate front side.
Described electricity component comprises slide rheostat, demonstration ammeter, and described magnet has multiple.
The invention has the beneficial effects as follows: 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, blackboard can connect into very large circuit, circuit diagram, operating process, experimental phenomena etc. are all that the full class in visual and clear ground is visible, be beneficial to raising learning interest, be beneficial to the explanation step by step to experimentation especially, teacher easily teaches, student is understandable, has larger promotional value.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
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, below it, substrate should be inlaid with multiple magnet 2.
For ease of being adsorbed on blackboard, battery 7 can select battery of mobile phone.
Claims (2)
1. a teaching demonstration magnetic electricity component, is made up of substrate and the electricity component being fixed on substrate front side, it is characterized in that: the bottom of described substrate is also inlaid with one or more magnet.
2. teaching demonstration magnetic electricity component as claimed in claim 1, it is characterized in that: described electricity component comprises slide rheostat, demonstration ammeter, described magnet has multiple.
