Specific embodiment
The technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described implementation
Example is only a part of embodiment of the invention, rather than whole embodiments.Based on the embodiment in the present invention, this area is common
The every other embodiment that technical staff is obtained under the premise of creative work is not made, belongs to the model of present invention protection
Enclose.
Core of the invention is to provide a kind of magnetic life audio-visual education programme tool, in order to more directly perceived, obvious demonstration magnetic life electrical phenomena.
Refer to Fig. 1, Fig. 2.A kind of magnetic life audio-visual education programme tool, including power transmission shaft 7, coil 1, magnet 2, light emitting diode 3, chassis
4th, support 5, rotating shaft 6 and control stick 8, power transmission shaft 7 sequentially pass through support 5, coil 1, magnet 2 and are movably arranged on chassis 4, line
Circle 1 is fixed on support 5, and magnet 2 is fixed in rotating shaft 6, and the two ends of light emitting diode 3 are connected with the two ends of coil 1 respectively, control stick
8 coordinate with power transmission shaft 7 in a state of use, pull rotating shaft 6 to rotate.
Used as specific embodiment, the control stick 8 is the bow-shaped structural that elastic bamboo chip and rubber band are constituted, the top of power transmission shaft 7
Fixed pulley is fixed with, rubber band coordinates with fixed pulley.
Used as specific embodiment, the coil 1 is the copper coil of 700 circles.
Used as specific embodiment, the light emitting diode 3 is three light emitting diodes of series connection.
Operating instruction of the invention：
Control stick 8 is placed on power transmission shaft 7, using the friction of the rubber band drive link on control stick 7, reciprocal behaviour before and after realizing
Make to change magnetic flux in coil 1, so as to produce induction field, and then electric currents are provided to three light emitting diodes 3 of series connection.This
Part can obtain 5-7 volt voltage, much larger than the voltage that the easy hand generator that usual student is used sends, be by
It is the bow-shaped structural constituted using elastic bamboo chip and rubber band of innovation in control stick 8, any of control stick 8 is gently rotated with hand
End, make use of the amplification of lever；Simultaneously because the relative motion increase friction of control stick 8 and power transmission shaft 7, just obtains quick
The magnetic flux of change, obtains output voltage higher, reaches self-control generating function and uses standard, can further be modified to
Electric device part in life, it may also be used for the low voltage power supply control end of large-scale scientific equipment.
Operating procedure：
(1) it is placed on the fixed pulley of top with arch control stick；
(2) cycle rotates pulley toward multiplexing bar before and after；
(3) magnet concomitant rotation, coil inside produces induced-current, LED operation.
Induced electric field average voltage produced by this part is about 7v, powers to the light emitting diode of 3 series connection.Experiment
The alternating it was found that diode flickers, it may be verified that what is produced in coil is alternating current.The process for being generated electricity in student oneself experience simultaneously
In, it is filled with enjoyment.
In teaching process, innovative design torsional mode generator dexterously utilizes friction and the amplification of lever to the application
Principle, excites student to seek knowledge potentiality, cultivates scientific literacy.According to the cognitive law of people, learn feelings with reference to the requirement of class mark and student and set
Meter, operation is easy to for imparting knowledge to students, and can reach good using effect.
The above is only the preferred embodiment of the present invention, rather than its limitations；Although it should be pointed out that with reference to above-mentioned each
Embodiment has been described in detail to the present invention, it will be understood by those within the art that, it still can be to above-mentioned each
Technical scheme described in embodiment is modified, or carries out equivalent to which part or all technical characteristic；And this
A little modifications and replacement, do not make the scope of the essence disengaging various embodiments of the present invention technical scheme of corresponding technical scheme.
