Abstract
Molecular force simulation experiment instrument, be simulative experimental instrument in physical teaching course, its principal feature is made up of two large slim magnet 3 varied in size and little slim magnet 4, electronic table dynamometer 12, objective table 5, deck 6, carrier base 7, support 10, bracket adjustment knob 9 and two beads (1,2).Electronic table dynamometer 12 horizontal positioned, objective table 5 fixed placement is on electronic table dynamometer 12, large slim magnet 3 is allowed to be fixed on objective table 5, carrier base 7 lower end is fixed on electronic table dynamometer 12 base, carrier base 7 upper end is by bracket adjustment knob 9 connection bracket 10, Fixing clamp-seat 6 on rack cross-bar 8, little slim magnet 4 is fixed with deck 6, large slim magnet 3 faces with little slim magnet 4 magnetic pole of the same name, large slim magnet 3 is with little slim magnet 4 vertically same central symmetry axis, two beads (1, 2) be separately fixed at along on two magnet of vertical axes right opposite, the distance between two magnet is changed by bracket adjustment knob, the change of observation power.
Description
Technical field
The present invention relates to the simulative experimental instrument in physics teaching field.
Background technology
In physical teaching course, intermolecular interaction force relation is one of elusive physical knowledge of student, the intermolecular force content of courses is very abstract, indigestibility, and the understanding of student to abstract intermolecular force is helped in the simulated experiment that present stage does not emulate.
Summary of the invention
The object of the invention is to be, the funtcional relationship that the model molecule intermolecular forces size of emulation and intermolecular distance change, allow student can be familiar with and understand very abstract physical concept intuitively, improve the ability that student uses one's hands and brains, analyzes problems and solves them.
Technical scheme of the present invention is: molecular force simulation experiment instrument, and the slim magnet varied in size by two, electronic table dynamometer, deck, objective table, support, rack cross-bar, carrier base, bracket adjustment knob and two beads form.Electronic table dynamometer horizontal positioned, objective table fixed placement is on electronic table dynamometer, large slim magnet is allowed to be fixed on objective table, carrier base lower end is fixed on electronic table dynamometer base, carrier base upper end is by bracket adjustment knob connection bracket, Fixing clamp-seat on rack cross-bar, little slim magnet is fixed with deck, large slim magnet faces with little slim magnet magnetic pole of the same name, large slim magnet is with little slim magnet vertically same central symmetry axis, two beads are separately fixed at along on two magnet of vertical axes right opposite, the distance between two magnet is changed by bracket adjustment knob, the change of observation power.
The further technical scheme of the present invention is: large slim magnet can be square magnet, can be patty magnet, can be circular ring type magnet, and the thickness of large slim magnet is no more than 1/2nd of width.
Little slim magnet can be square magnet, can be patty magnet, can be circular ring type magnet, and the thickness of little slim magnet is no more than 1/2nd of width.
The width of little slim magnet is no more than the width 1/2nd of large slim magnet.
The present invention further technical scheme is: the vertical bar of support has rule.
The present invention further technical scheme is: bead can not be that the magnetic materials such as iron, cobalt, nickel are made.
Basis of the present invention is: slim size two magnet magnetic pole of the same name is relative, along axis of symmetry by far in nearly moving process lentamente, interactional magnetic field force, first be expressed as that repulsion is ascending to diminish to zero again, then show as gravitation ascending, and magnetic field force size forms the change of geometry multiple with spacing minimizing.
Below in conjunction with the drawings and specific embodiments, detailed content of the present invention is further described.
Accompanying drawing explanation
Fig. 1 is the structural representation of molecular force simulation experiment instrument of the present invention.
