It is to be inconvenient to demonstrate in solid.
Summary of the invention
In order to solve the problems referred to above that prior art exists, this utility model provides a kind of magnetic induction line space demonstrator,
Can facilitate and demonstrate on classroom, this demonstrator structure is simple, it is also possible to allows student do it yourself to make, can either enrich
The content of courses, deepens the understanding of student；And this device can be used together in conjunction with multimedia teaching facilities such as projectors.
The technical scheme that this utility model is used is: a kind of magnetic induction line space demonstrator, including: Magnet, body and gold
Belong to silk, described Magnet be arranged on described internal, described tinsel by show post be fixed on the side of described body, described
Body is fixed with the plane parallel of described side wiry and the both positive and negative polarity place of described Magnet.
The further optimization of technical solutions of the utility model, described bar number wiry is no less than five, described metal
Between Si separate, and a plurality of described tinsel is evenly distributed on the side of described body ringwise.
The further optimization of technical solutions of the utility model, described tinsel is metal fiber wire or metallic bond.
The further optimization of technical solutions of the utility model, described body is tubular, and described tinsel is fixed on described
On the bottom surface of body, described Magnet is arranged in the chamber of described body tubular.
The further optimization of technical solutions of the utility model, described body is made by bottle cap, described tinsel be ferrum,
One or any multiple combination in cobalt, nickel.
The further optimization of technical solutions of the utility model, one end of described displaying post connects has tinsel, the other end to wear
Cross the side of described body, and fixing on the body by paraffin.
The beneficial effects of the utility model are:
(1) the distribution feelings of space magnetic induction line are explored in the comprehensive infiltration the most progressively from the one-dimensional space to three dimensions of this set teaching aid
Condition, is more conducive to training student problem analysis problem-solving ability；
(2) design that this set teaching aid is demonstrated at three dimensions magnetic induction line, has broken the fixing think of that traditional learning aid is formed
Dimension, is more conducive to student and understands that magnetic induction line is distributed, and also reaches the purpose that stimulus interests cultivates one's ability simultaneously.
(3) this set teaching aid, simple to operate, easy to carry, and phenomenon substantially and uses safe feature.
(4) it both can carry out lecture experiment in conjunction with multimedia equipment, comes from life, low cost because of its main material again
Honest and clean, it is possible to staff is a set of turns on grouping experiment.Embody physics and come from life, return the essence of life.
(5) the most bootable encouragement student, does it yourself from making teaching aid, thus has reached the purpose taught through lively activities.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model magnetic induction line space demonstrator；
Fig. 2 is the demonstration top view of this utility model magnetic induction line space demonstrator.
In figure: 1, body；2, Magnet；3, post is shown；4, tinsel.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, below will be to technology of the present utility model
Scheme is described in detail.Obviously, described embodiment is only a part of embodiment of this utility model rather than all
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not before making creative work
Put obtained other embodiments all, broadly fall into the scope that this utility model is protected.
As depicted in figs. 1 and 2, this utility model provides a kind of magnetic induction line space demonstrator, including: Magnet 2, body 1
With tinsel 4, Magnet 2 is arranged in body 1, and tinsel 4 is by showing that post 3 is fixed on the side of body 1, and body 1 is fixed
There is the plane parallel of the side of tinsel 4 and the both positive and negative polarity place of Magnet 2.Tinsel 4 can be made to show magnetic induction line completely
Distribution, by showing that post 3 connects tinsel 4, facilitate tinsel 4 to carry out point according to the direction in magnetic field under the action of a magnetic force
Cloth.
One end of described displaying post connects tinsel, and the other end is through the side of described body, and is fixed by paraffin
On the body, when body is fabricated to by bottle cap, show the post capping through bottle cap, easily unstable, pass through in inner side
Paraffin is fixing can increase the stability showing post, makes bandwagon effect the most stable.
The bar number of tinsel 4 is no less than five, separate between tinsel 4, and many wire 4 are the most uniform
It is distributed on the side of body 1, owing to Distribution of Magnetic Field is to be sent by the positive pole of Magnet 2, is then return to the negative pole of Magnet 2, passes through
Being provided in tinsel 4 annular on the side that magnetic pole is parallel, it is possible to the convenient distribution observing whole magnetic field, shows result
The most comprehensive.
Tinsel 4 is metal fiber wire or metallic bond, and the weight of tinsel 4 is difficult to excessive, prevents due to tinsel 4
Weight and affect bandwagon effect, use the metallic bond made of tinsel 4 of metallic fiber or thinner, it is possible in the effect in magnetic field
Under make the free end of tinsel 4 be subjected to displacement along the direction in magnetic field, thus combine all of tinsel 4 and show comprehensive magnetic field
Effect.
Body 1 is in tubular, and tinsel 4 is fixed on the bottom surface of body 1, and Magnet 2 is arranged in the chamber of body 1 tubular,
Preferably body 1 one end one straight opening, Magnet 2 can be placed and taken out freely, so can during demonstration,
By taking out Magnet 2 and putting Magnet 2 generation contrast into, thus understand the distribution in magnetic field.
Body 1 is for be made by bottle cap, and tinsel 4 is the one or any multiple combination in ferrum, cobalt, nickel, for
Operability in the convenience of teaching and field research, uses the bottle cap being easiest to touch in life, also is able to religion simultaneously
Educate student economize on resources and make full use of resource.
The above, detailed description of the invention the most of the present utility model, but protection domain of the present utility model does not limit to
In this, any those familiar with the art, in the technical scope that this utility model discloses, can readily occur in change
Or replace, all should contain within protection domain of the present utility model.Therefore, protection domain of the present utility model should be described with power
The protection domain that profit requires is as the criterion.
