Description
Technical field
The utility model relates to a kind of experiment device for teaching, is a kind of stressed experimental provision that is used for physics teaching in secondary school experiment electrical conductor in magnetic field.
Background technology
At present, in physics teaching in secondary school,,, can give that a kind of misleading of student---magnetic field is to the strong effect of hot-wire coil though the demonstration effect is obvious with style of the shoe magnet and coil demonstration motor principle; The teacher who has utilizes masking foil to make columned conductor and style of the shoe magnet is demonstrated, stressed the moving of energising back column masking foil, because quality alleviates and makes mobile phenomenon obvious, but easily contact bad during the masking foil energising with guide rail, at contact point even generation electric spark, damage masking foil, make it short with the life-span.The self-control experimental provision experiment effect that has is difficult to guarantee, and exists interesting poor, and operation is inconvenient, defective such as lose time.Now, a kind of price is low, easy to operate, the typing experimental provision of good demonstration effect because do not have, and makes the effect of experiment uneven.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, the demonstration effect is obvious, use cost is low, simple to operate, be convenient to the stressed experimental provision of electrical conductor in magnetic field popularizing and promote.
The purpose of this utility model can realize by following technical measures:
The stressed experimental provision of electrical conductor in magnetic field, by binding post, metal guide rail, zinc pipe, insulating support, magnet, power supply is formed, its insulating support is installed on the base, insulating support has the pillar that raises up at base four jiaos, forwardly with on two pillars at rear portion be separately installed with a metal guide rail, before and after two metal guide rail be positioned on the same surface level and parallel with the upper plane of base, metal tube across two guide rails is arranged at the top of two metal guide rail in front and back, the upper plane of base is provided with the magnet of cuboid, there is binding post end in metal guide rail, two metal guide rail in front and back have switch by binding post and lead and power series in sequential circuit.
The purpose of this utility model can also realize by following technical measures:
Metal guide rail of the present utility model is a cylindrical aluminium alloy guide rail, and metal tube is a zinc pipe, the width of the magnet of cuboid greater than or equal before and after width between two metal guide rail.
Metal tube of the present utility model is the thin skin zinc pipe, and metal guide rail is the cylindrical aluminium alloy guide rail of thin skin body shape.
The top of the magnet of the utility model cuboid is that " N " utmost point bottom is " S " utmost point, or the top of the magnet of cuboid is that " S " utmost point bottom is " N " utmost point.
The utility model compared with prior art has following advantage:
1, usefulness zinc pipe material prolongs its life-span as mobile conductor, and the rectangular parallelepiped of magnetic field intensity usefulness 1000H-1300H (can test with No. 1 common dry cell (2 joint), and effect is very obvious by 85 * 65 * 17mm) magnet.
2, easy to operate, save experimental period, experiment effect is good.
3, can be used as a kind of typing experimental provision, use repeatedly, experimental cost is extremely low, is convenient to popularize and promote.
