Description
Technical field
The utility model relates to a kind of physics teaching aid, specifically a kind of simple and easy electromagnetic induction teaching demonstration device.
Background technology
In present physics teaching, electromagnetic induction is one of important content, traditional method is that one of employing or two blocks of style of the shoe magnet keep flat, stop up the simulation solid conductor with multiturn coil again, do the magnetic line of force motion of cutting style of the shoe magnet, because equipment is simple, when doing experiment, need interim assembling, cause and carry inconvenience, observations is not obvious, and the demonstration effect of teaching is undesirable, thereby electromagnetic induction teaching can only be rested on the imagination to theory, the student can not understand theoretical implication intuitively, has reduced the efficient of study.
Summary of the invention
The purpose of this utility model is to provide a kind of compact conformation, easy to carry, and the demonstration effect is obvious, can improve the simple and easy electromagnetic induction teaching demonstration device of student's learning interest.
In order to reach above purpose, the technical scheme that the utility model adopted is: this simple and easy electromagnetic induction teaching demonstration device, by galvanometer, the galvanometer mounting box, last magnet, lower magnet, coil twines frame and conductive pole constitutes, conductive pole is connected with galvanometer by lead, galvanometer is fixed in the galvanometer mounting box, it is characterized in that magnet mounting box and lower magnet mounting box on fixing on the right side wall of galvanometer mounting box, on, lower magnet is separately fixed at, in the lower magnet mounting box, make, the relative magnetic pole of lower magnet attracts each other, fixing two conductive poles on the top panel of lower magnet mounting box, the all sheathed conducting ring of going up on the outer wall of the dwang at coil winding frame two ends, two conducting rings are set in respectively in the through hole on two conductive pole tops, coil twines frame and dwang is all made by insulating material, enameled wire is wrapped in coil and twines on the frame, two terminations of enameled wire are welded on respectively on two conducting rings, when rotating coil twines frame at leisure, the coil cutting magnetic induction line that enameled wire surrounds, produce electric current, pass to galvanometer through conducting ring and conductive pole, galvanometric pointer produces swing, and showing has electric current to produce.The utility model is also implemented by following measure: the fixing crank of going up in the outer end of described dwang, twine frame to make things convenient for the testing crew rotating coil.In use, only need the utility model is placed on the testing table, rotate crank, coil twines frame and is offset, cutting magnetic induction line, and the galvanometric beat of pointer, showing has electric current to produce in the coil.
The beneficial effects of the utility model are: compact conformation, easy to carry, the electromagnetic induction demonstration effect is obvious, has improved students'interest in learning.
