Abstract
The utility model relates to the field of electromagnetic knowledge teaching demonstration instruments and discloses a suspension-type electromagnetic force demonstration instrument, thereby solving the problem that conventional electromagnetic force demonstration instruments are complex in structure. The suspension-type electromagnetic force demonstration instrument comprises a fixing pedestal, a first pressing piece, a second pressing piece, a first support, a second support, a movable straight conductor, a U-shaped magnet, and a power line. The second support is pressed by the second pressing piece and closely attached to the inner side wall of the second pressing piece, and then screws are used to fix the second pressing piece. The movable straight conductor is suspended on the first support and the second support and disposed in the U-shaped magnet. The first support is pressed by the first pressing piece and closely attached to the inner side wall of the first pressing piece, and then screws are used to fix the first pressing piece. The suspension-type electromagnetic force demonstration instrument is suitable for electromagnetic knowledge teaching demonstration.
Description
Technical field
The utility model is a kind of demonstration instrument using in electromagnetism knowledge teaching, specifically can in magnetic field, can be subject to the effect of electromagnetic force with the conductor of this utility model checking energising exactly.
Background technology
The primary structure of demonstrator for electromagnetic force is comprised of the conductor that can switch on and magnetic field two large divisions nothing but exactly, but, the demonstrator for electromagnetic force that can buy on current domestic instruments used for education market, magnetic field is wherein to be provided by hot-wire coil, and be encapsulated in iron-clad, from the appearance Bu Chushi magnetic field, learner is not easy to understand, teacher also need do to explain at this simultaneously, brings unnecessary trouble.So the utility model has solved the problem of above existence, and all right self manufacture of user, not only economy but also practicality.
Summary of the invention
The utility model technical issues that need to address are, overcome the deficiency of background technology, provide a kind of simple and reasonable, and practical demonstrator for electromagnetic force directly perceived.The utility model has mainly adopted structural framing the most intuitively, thereby solved learner, owing to understanding the origin in magnetic field, does not affect normal learning content.
Suspended electromagnetic power demonstrator described in the utility model, described suspended electromagnetic power demonstrator comprises firm banking, the first compressing tablet, the second compressing tablet, the first support, the second support, movable straight conductor, U magnet, power lead and the second compressing tablet, second pushes down the second support, and the second support is adjacent to the second compressing tablet madial wall, by screw, fix the second compressing tablet again, movable straight conductor is suspended on the first support and the second support, movable straight conductor is placed in U magnet inside, the first compressing tablet is pushed down the first support, and the first support is adjacent to the first compressing tablet madial wall, by screw, fix the first compressing tablet again.
The utility model is that the concrete technical scheme solving the problems of the technologies described above is, agent structure is comprised of base, support, suspension type conductor, power supply plug wire and U-shaped magnet: base adopts the thick iron plate of 1cm to be growth 15.5cm, wide for 6.5cm, high for 2.5cm shape, plays fixation; It is 2.5mm that support adopts sub-thread wire diameter
2naked hard aluminum wire is made two erect-type supports, and one end is fixed on base, and the other end is done circular hook (can coat some lubricating oil), mainly plays the effect of supported and suspended electrical conductor, and another effect is conduction; Suspension type conductor is identical with the material that support adopts, and is all that sub-thread wire diameter is 2.5mm
2naked duralumin wire processed, the conductor of making swing shape hangs on support; Power supply plug wire is connected on the tie point place of support and base, for the effect to conductor energising; U-shaped magnet mainly provides the effect in magnetic field to electrical conductor, actual with time can regulate by increasing and decreasing the quantity of U-shaped magnet the power in magnetic field.
The utility model has the advantages that: 1. practical, the content that the utility model will embody is that junior physics or secondary vocational school's electricity specialty must be used, and can teacher bring great convenience, improves teaching efficiency.2. simple in structure, be easy to manufacture, and cost of manufacture is low, user can self manufacture.
