Abstract
The utility model provides an experiment apparatus for magnetism can effective, audio -visually reflect not magnetic force magnitude under the same distance, makes things convenient for the teacher to demonstrate and understands with the student, the utility model discloses well casing both ends are installed the threaded rod respectively, are conducted the pole, and the knob is connected to threaded rod one end, and the initiative magnetic path is connected to the other end, conduction pole one end coupling spring balance, and the passive magnetic path of other end connection, the utility model has the characteristics of the design is simple, convenient operation, and the result shows directly perceivedly, can show abstract magnetic force change remarkable's the hanging spring -balance scale that passes through.
Description
Technical field
The present invention relates to Physical Education teaching experimental device, specifically a kind of experiment apparatus for magnetism.
Background technology
In with regard to the Physical Education teaching of magnetic, it is a kind of general knowledge rule that homopolar-repulsion, heteropole be attracting, but existing education
Teaching equipment can not effectively, intuitively reflect the size of the repulsion that magnetic force produced under different distance and suction, therefore design one
Plant distance in can intuitively embodying magnetic force experiment to be particularly important the presentation device of magnetic force size.
The content of the invention
The invention provides a kind of experiment apparatus for magnetism, can effectively, intuitively reflect magnetic force size under different distance,
Teacher's demonstration and student is facilitated to understand.
What the present invention was realized in：Active magnetic piece and passive magnetic piece, the left plate and right plate of housing are set in housing
On be separately installed with threaded rod, conductive bar, threaded rod outer end connection knob, inner connection active magnetic piece, the connection of conductive bar outer end
Spring scale, it is inner to connect passive magnetic piece.
Housing is non magnetic housing or permeability magnetic material housing.
The invention has the beneficial effects as follows：Design is simple, easy to operate, as a result intuitive display, can be by abstract magnetic force change
Obviously shown by spring scale scale.
Description of the drawings
It is described further below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the present invention.
1, knob in figure, 2, threaded rod, 3, housing, 4, conductive bar, 5, spring scale, 6, active magnetic piece, 7, passive magnetic piece.
Specific embodiment
As illustrated, 3 two ends of housing are respectively mounted threaded rod 2, conductive bar 4,2 one end of threaded rod connection knob 1, the other end
Connection active magnetic piece 6,4 one end connecting spring scale 5 of conductive bar, the other end connects passive magnetic piece 7.
When being tested, rotary knob 1, threaded rod 2 are rotated with knob 1, and active magnetic piece 6 is slow near passive magnetic piece 7,
Now, the suction or repulsion being subject between active magnetic piece 6 and passive magnetic piece 7 passes to spring scale 5 by conductive bar 4, with actively
Between magnetic piece 6 and passive magnetic piece 7, distance is continually changing, and the suction or repulsion between two pieces of magnetic piece is by the number on spring scale 5
Reflected according to scale in real time, Faculty and Students can pass through the reading for measuring the distance between two pieces of magnetic piece and spring scale 5
It is to carry out magnetic force change calculating, visual in image, it is easy to teachers ' teaching and student to understand.
To prevent impact of the housing to this experimental provision, housing 3 is non magnetic housing or permeability magnetic material housing.
