Description
Technical field
The present invention relates to a kind of popular science knowledge apparatus for demonstrating, specifically the apparatus for demonstrating of electromagnetic induction.
Background technology
Second (Senior Two) the 16 chapter first segment (P194) of high school physics: no matter be that a part of conductor of closed circuit is done the cutting magnetic induction line motion, or the magnetic field in the closed circuit changes, and the magnetic flux that passes closed circuit all changes.
No matter how, change as long as pass the magnetic flux of closed circuit, just there is electric current to produce in the closed circuit.This phenomenon of utilizing magnetic field to produce electric current is called electromagnetic induction, and the electric current of generation is called induction current.
Summary of the invention
The purpose of this utility model is the apparatus for demonstrating of a kind of electromagnetic induction of design.
The concrete structure design proposal is as follows:
The apparatus for demonstrating of electromagnetic induction, structure comprises Demonstration table, parallelly on Demonstration table is provided with two permanent magnet supports, and two stands is provided with horizontal rotating shaft, and horizontal rotating shaft is provided with permanent magnet, and horizontal rotating shaft one end is overhanging, and its overhanging end is provided with handwheel; On the Demonstration table between two permanent magnet supports, be provided with coil brace, coil brace is provided with coil, is provided with handle in the coil brace outside, and handle is connected with coil, also be provided with fluorescent tube on Demonstration table, coil and fluorescent tube connect into the circuit that meets the electricity rule by lead.
Useful technique effect of the present utility model is embodied in following aspect:
The utility model both can be used for the science popularization venue, the science and technology center of flowing, and as the science popularization showpiece, also can be used for middle school physical curriculum, as a kind of aided education experiment product, can visual in image ground demonstrating electromagnetic induction phenomenon, and be convenient to the understanding of student's intensification to electromagnetic induction.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is a vertical view of the present utility model.
Embodiment:
During use, producing induction current has two kinds of methods, and below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment:
The apparatus for demonstrating of electromagnetic induction, structure comprises Demonstration table, parallelly on Demonstration table is provided with two permanent magnet support 2 (see figure 1)s, two stands 2 is provided with horizontal rotating shaft 8, horizontal rotating shaft 8 is provided with permanent magnet 1, and horizontal rotating shaft 8 one ends are overhanging, and its overhanging end is provided with handwheel 6; On the Demonstration table between two permanent magnet supports 2, be provided with coil brace 5, coil brace 5 is provided with coil 4, be provided with handle 7 (see figure 2)s in coil brace 5 outsides, handle 7 is connected with coil 4, also be provided with fluorescent tube 3 on Demonstration table, coil 4 and fluorescent tube 3 connect into the circuit that meets the electricity rule by lead.
Following two kinds of methods are arranged during use:
1. hold handle 7 moving coils 4, make coil 4 cutting magnetic lines produce induction current, fluorescent tube 3 promptly can be luminous.
2. when coil 4 and magnet 1 relative when motionless, rotate handwheel 6, allow magnetic field in the coil 4 generation induction current that changes, fluorescent tube 3 promptly can be luminous.
