Abstract
The utility model discloses a novel permanent magnet suspension demonstrating instrument, which is mainly used in the field of teaching demonstration and the like. The permanent magnet suspension demonstrating instrument comprises a plurality of cubic permanent magnets with same size and same magnetic intensity, wherein the S poles (or N poles) of the cubic permanent magnets are placed downwards between a lower baffle plate and an upper baffle plate, the lower baffle plate and the upper baffle plate are horizontally fixed in the middle portion of a bracket, distance between the inner surfaces of the lower baffle plate and the upper baffle plate is larger than twice and smaller than square root of two times of side length of the cubic permanent magnet, therefore the cubic permanent magnet is capable of freely moving without turning between the lower baffle plate and the upper baffle plate, the lower baffle plate, and the upper baffle plate and the bracket are all made of transparent materials. The cylindrical permanent magnet is fixed at central position of the upper surface of a base, and the S pole (or N pole) of the cylindrical permanent magnet faces upward. The novel permanent magnet suspension demonstrating instrument can demonstrate magnetic suspension due to gravity offset by like magnetic pole repulsive force or unlike magnetic pole attractive force between the permanent magnets.
Description
Technical field:
The utility model relates to a kind of use permanent magnet and produces maglev teaching demonstration apparatus.
Technical background:
Along with development of times, magnetic levitation technology is come into people's life gradually, and the fastest public transport in especially current land---magnetic suspension train causes that especially people's attention is with curious.In teaching process, how this excites the juvenile science science, uses the interest of science, allow them understand the change that maglev ultimate principle and magnetic levitation technology bring for daily life more? teaching demonstration equipment by novelty often can reach the effect of getting twice the result with half the effort, and the teaching demonstration equipment that generally uses in the present middle and primary schools teaching process only is some bar-shaped magnets, U type magnet or electromagnet, lack interest with these equipment teaching demonstrations, classmates' impression is not dark; Have only to university, part colleges and universities have just introduced the super-conductive magnetic suspension demo system and have been used for teaching, and this equipment can be demonstrated the basic structure and the superconducting phenomenon of maglev ultimate principle, magnetic suspension train well, is subjected to academics and students's favorable comment.But also there is defective in the super-conductive magnetic suspension demo system: at first cost an arm and a leg, institution of higher learning still can bear, and middle and primary schools just are difficult to accept; Next need produce ultralow temperature with liquid helium when being the operation of this system, has certain risk, and superconductor deposit to around environmental requirement very harsh, be difficult to keeping.
Summary of the invention:
In order to better meet the teaching needs, the utility model provides a kind of novel permanent magnetic suspension demonstrator, like pole repulsive force or opposite pole attractive force that this device can be demonstrated between permanent magnet have intuitively been offset gravity and have been produced maglev phenomenon, can motivate students' interest in learning, and its low price, be convenient to popularize.
The technical scheme that its technical matters that solves the utility model adopts is: square permanent magnet a plurality of sizes are identical and that magnetism intensity is identical is placed between two baffle plates, and the S utmost point of all square permanent magnets (or N utmost point) all down; The spacing of two baffle inner surface is greater than 1 times of the length of side of square permanent magnet and less than the length of side of square permanent magnet
Doubly, make the square permanent magnet can be free between two baffle plates movable and can not overturn, two baffle plates all be horizontally fixed on mid-stent, and baffle plate and support are all made with transparent material; A cylindrical permanent magnet is installed at the base upper surface center, and the S utmost point of this cylindrical permanent magnet (or N utmost point) also is carved with a groove that mates with support up on the base, makes support can put into groove just and avoids sliding.During use, support can be placed on the top of base, make cylindrical permanent magnet and square permanent magnet form the like pole state that repels each other, the gravity that the repulsive force that is produced has been offset the square permanent magnet is suspended in the square permanent magnet in the air; Also base can be buckled in conversely the top of support, make cylindrical permanent magnet and square permanent magnet form the opposite pole attracting state, the gravity that the attractive force that is produced has been offset the square permanent magnet is suspended in the square permanent magnet in the air; And a plurality of square permanent magnets also the are like pole each other state that repels each other can not be adsorbed on one, and its magnetism intensity is identical, finally can form an equilibrium state.
The beneficial effects of the utility model are: the demonstration effect is obvious, the presentation process vivid and interesting.Like pole repulsive force that forms between square permanent magnet and the cylindrical permanent magnet or opposite pole attractive force have been offset self gravitation and have been suspended in aerial, rock the utility model gently, a plurality of square permanent magnets are swing aloft just, and between all square permanent magnets the like pole state that repels each other, always keep certain distance each other, finally can reach equilibrium state.The utility model is simple in structure, the prices of raw and semifnished materials are cheap, is convenient to popularize.
Description of drawings:
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a cross-section front view of the present utility model.
Each label list is shown among the figure:
1. base 2. supports 3. cylindrical permanent magnet
4. lower baffle plate 5. overhead gages 6. square permanent magnets
Embodiment:
In cross-section front view of the present utility model shown in Figure 1, the S utmost point of a plurality of square permanent magnets 6 (or N utmost point) is all towards being placed down between lower baffle plate 4 and the overhead gage 5, lower baffle plate 4 and overhead gage 5 all are horizontally fixed on the middle part of support 2, and the spacing of lower baffle plate 4 and the inside surface of overhead gage 5 is greater than 1 times of the length of side of square permanent magnet 6 and less than the length of side of square permanent magnet 6
Doubly, make that square permanent magnet 6 can be free movable between lower baffle plate 4 and overhead gage 5 and can not overturn, lower baffle plate 4, overhead gage 5 and support 2 are all made by transparent material, a cylindrical permanent magnet 3 is fixed in the upper surface center of base 1, the S utmost point of cylindrical permanent magnet 3 (or N utmost point) up, also dig the groove that has to mate on the base 1, make support 2 can put into groove just and avoid sliding with support 2.
During use, support 2 can be placed on the top of base 1, make cylindrical permanent magnet 3 and a plurality of square permanent magnets 6 form the like poles state that repels each other, the gravity that the repulsive force that is produced has been offset square permanent magnet 6 is suspended in square permanent magnet 6 in the air; Also base 1 can be buckled in conversely the top of support 2, make cylindrical permanent magnet 3 and a plurality of square permanent magnet 6 form the opposite pole attracting state, the gravity that the attractive force that is produced has been offset square permanent magnet 6 is suspended in square permanent magnet 6 in the air; And a plurality of square 6 permanent magnets also the are like pole each other state that repels each other can not be adsorbed on one, and its magnetism intensity is identical, finally can reach an equilibrium state.
