Description
Technical field
The present invention relates to Popular Science Education technical field, more particularly to a kind of teaching aid for demonstrating magnetic life electrical phenomena.
Background technology
Magnetic life electrical phenomena is that British scientist faraday has found that its principle is that a part of conductor of closed circuit is cut
When magnetic induction line moves, the phenomenon of electric current will be produced on conductor, this phenomenon is referred to as electromagnetic induction phenomenon by we, is produced
Electric current be called induced-current.Generator is according to made of this principle.In the prior art, for individually demonstrating magnetic life
The teaching aid species of electrical phenomena is various, 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 magnitude relationship is really rare, therefore, present invention proposes a kind of magnetic of demonstrating to give birth to electrical phenomena
Teaching aid, it can not only illustrate electromagnetic induction phenomenon by simple and clear phenomenon to spectators, additionally it is possible to allow student learning
The relation of conductor cutting magnetic induction line speed and induced-current size is probed into journey.
The content of the invention
It is an object of the invention to a kind of demonstration magnetic for overcoming problems of the prior art and providing life electrical phenomena
Teaching aid.
In order to solve the above technical problems, the present invention adopts the following technical scheme that：
A kind of teaching aid for demonstrating magnetic life electrical phenomena, including table top and the apparatus for demonstrating that is located on the table top, the apparatus for demonstrating
Including the mounting bracket on the table top, rotary shaft is provided with the mounting bracket, is provided with the rotary shaft
Copper dish, the copper dish are engraved structure, and magnet is respectively equipped with the both sides of the copper dish, and the magnet is arranged on magnet holder
On, the magnet holder is fixed on the stage body, is additionally provided with an ammeter on the stage body, the ammeter with it is described
Copper dish connect and form loop.
Preferably, a manual setter is additionally provided with the table top, the manual setter passes through timing belt and the rotation
Axle is connected.
Compared with prior art, beneficial effects of the present invention are：
The present invention it is a kind of demonstrate magnetic life electrical phenomena teaching aid, by using engraved structure copper dish magnet magnetic field internal rotation,
In copper dish rotary course will cutting magnetic induction line, the ammeter for being now connected with copper dish and forming loop can produce electric current, from
And demonstrate magnetic life electrical phenomena；Change the registration change of speed, again observation ammeter that copper dish rotate by manual setter, can enter
One step research copper dish rotating speed and faradic magnitude relationship.
