Abstract
A molecular force simulation experiment instrument is used in the process of physics teaching and mainly characterized by being composed of a large thin magnets (3), a small thin magnet (4), a desk type electronic dynamometer (12), an objective table (5), a clamping base (6), a support base (7), a support (10), a supporting adjusting knob (9) and two small balls (1and 2). The desk type electronic dynamometer (12) is horizontally placed, the objective table (5) is fixedly placed on the desk type electronic dynamometer (12), the large thin magnet (3) is fixed on the objective table (5), the lower end of the support base (7) is fixed on a base of the desk type electronic dynamometer (12), the upper end of the support base (7) is connected with the support (10) through the support adjusting knob (9), the clamping base (6) is fixed on a support transverse rod (8), the small thin magnet (4) is fixed through the clamping base (6), and same magnetic poles of the large thin magnetic (3) and the small thin magnet (4) are over against. Along the same central symmetry axis in the vertical direction, the large thin magnet (3) and the small thin magnet (4) fix the two small balls (1 and 2) on the two magnets over against along the vertical axis respectively, the distance between the two magnets is changed through the support adjusting knob, and force changes are observed.
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 present stage does not have the simulated experiment of emulation to help the understanding of student to abstract intermolecular force.
Summary of the invention
The objective of the invention is to be, between the model molecule of emulation, acting force size and the funtcional relationship that intermolecular distance changes, allow the student can be familiar with intuitively and understand very abstract physical concept, improves the ability that the student uses one's hands and brains, analyzes problems and solves them.
Technical scheme of the present invention is: the molecular force simulative experimental instrument is comprised of two slim magnet that vary in size, desk-top electronic dynamometer, deck, objective table, support, rack cross-bar, carrier base, bracket adjustment knob and two beads.Desk-top electronic dynamometer horizontal positioned, the objective table fixed placement is on desk-top electronic dynamometer, allow large slim magnet be fixed on objective table, the carrier base lower end is fixed on desk-top electronic dynamometer base, the carrier base upper end is by bracket adjustment knob connection bracket, Fixing clamp-seat on rack cross-bar, with the fixing little slim magnet of deck, large slim magnet faces with little slim magnet magnetic pole of the same name, large slim magnet is followed vertically same central symmetry axis of little slim magnet, two beads are separately fixed at along on two magnet of vertical axes right opposite, change the distance between two magnet by the bracket adjustment knob, the variation 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's further technical scheme again is: on the vertical bar of support, rule is arranged.
The present invention's further technical scheme again is: bead can not be that the magnetic materials such as iron, cobalt, nickel are made.
Basis of the present invention is: slim big or small two magnet magnetic pole of the same name is relative, along axis of symmetry by far in moving process closely lentamente, interactional magnetic field force, first be expressed as that repulsion is ascending to diminish to zero again, then show as gravitation ascending, and the magnetic field force size reduces and forms how much multiples variations with spacing.
Below in conjunction with the drawings and specific embodiments, detailed content of the present invention is further described.
