Description
Technical field
The present invention relates to Popular Science Education technical field more particularly to a kind of teaching aids of the raw electrical phenomena of demonstration magnetic.
Background technique
The raw electrical phenomena of magnetic is British scientist faraday discovery, and principle is that a part of conductor of closed circuit is cut
When magnetic induction line moves, the phenomenon that will generate electric current on conductor, this phenomenon is referred to as electromagnetic induction phenomenon by we, is generated
Electric current be called induced current.Generator is according to made of this principle.In the prior art, raw for individually demonstrating magnetic
The teaching aid of electrical phenomena is many kinds of, but can demonstrate and student can also be allowed to probe into conductor cutting magnetic induction line in learning process
The teaching aid of speed and induced current size relation is really rare, for this purpose, present invention proposes a kind of raw electrical phenomenas of demonstration magnetic
Teaching aid, it can not only illustrate electromagnetic induction phenomenon to spectators by simple and clear phenomenon, additionally it is possible to student be allowed to learn
The relationship of conductor cutting magnetic induction line speed Yu induced current size is probed into journey.
Summary of the invention
A kind of raw electrical phenomena of the demonstration magnetic provided it is an object of the invention to overcome problems of the prior art
Teaching aid.
In order to solve the above technical problems, the present invention adopts the following technical scheme that:

Device includes the mounting bracket being mounted on the table top, rotary shaft is equipped in the mounting bracket, in the rotary shaft
Equipped with copper dish, the copper dish are engraved structure, are respectively equipped with magnet in the two sides of the copper dish, the magnet is mounted on magnetic catch
On tool, the magnet holder is fixed on the table top, and an ammeter, the ammeter and institute are additionally provided on the table top
Copper dish are stated to connect and constitute circuit.
Preferably, it is additionally provided with a manual setter in the table top, the manual setter passes through synchronous belt and the rotation
Axis is connected.
Compared with prior art, the invention has the benefit that
A kind of teaching aid of the raw electrical phenomena of demonstration magnetic of the present invention, by using engraved structure copper dish magnet magnetic field inward turning
Turn, in copper dish rotary course will cutting magnetic induction line, connect at this time with copper dish and the ammeter for constituting circuit can generate electric current,
To demonstrate the raw electrical phenomena of magnetic;Change the speed of copper dish rotation by manual setter, observes the registration variation of ammeter, energy again
Further research copper dish revolving speed and faradic size relation.

It is additionally provided with an ammeter 7, the ammeter 7 connect with the copper dish 4 and constitutes circuit.
Preferably, be additionally provided with a manual setter 8 in the table top 1, the manual setter 8 by synchronous belt 9 with it is described
Rotary shaft 3 is connected.
The teaching aid of the raw electrical phenomena of a kind of demonstration magnetic of the present invention, by using the copper dish 4 of engraved structure in the magnetic field of magnet 5
Rotation, in 4 rotary course of copper dish will cutting magnetic induction line, connect at this time with copper dish 4 and the ammeter 7 for constituting circuit can generate
Electric current, to demonstrate the raw electrical phenomena of magnetic;Change the speed that copper dish 4 rotate by manual setter 8, observes showing for ammeter 7 again
Number variation, can further study 4 revolving speed of copper dish and faradic size relation.Apparatus of the present invention not only pass through simple and clear
Phenomenon illustrates electromagnetic induction phenomenon to spectators, additionally it is possible to allow student probed into learning process conductor cutting magnetic induction line speed with
The relationship of induced current size.
The above description is only the preferred embodiments of the present invention, is not intended to limit the present invention in any other form,
Any person skilled in the art is changed or is modified as equivalent variations possibly also with the technology contents of the disclosure above
Equivalent embodiment.But without departing from the concept of the present invention, above embodiments are done according to the technical essence of the invention
Any simple modification, equivalent variations and remodeling, still fall within protection scope of the present invention.
