Abstract
The utility model discloses a rotary type left-hand rule teaching demonstration device. The rotary type left-hand rule teaching demonstration device comprises a conversion power supply, a circular ring-shaped magnet, a wire, a small copper sheet, an iron nail, a big copper sheet and a wooden block. One end of the conversion power supply is connected with the big copper sheet via the wire; the big copper sheet is wrapped around a side face of the circular ring-shaped magnet; the wooden block is clamped in the circular ring-shaped magnet; the iron nail is inserted in the wooden block; one end of the small copper sheet is threaded on the top end of the iron nail and the other end is in close contact with the edge of the big copper sheet; and the other end of the wire is connected with the iron nail and then is connected to the conversion power supply. Based on the above technical scheme, a user is capable of achieving an effect that an electrified conductor bears an ampere force in magnetic field via simple circuit connection and switching on and off; and compared with a former curriculum demonstration device, the rotary type left-hand rule teaching demonstration device is easier to use and simpler in operation, and phenomena are more observable.
Description
Technical field
The utility model relates to a kind of instrument field of senior middle school physics teaching demonstration, is specifically related to a kind of rotary left-hand rule teaching demonstration device that can be used as demonstration use.
Background technology
Along with going deep into of the reform of educational system, secondary school education is more and more focused on the cultivation of initiative spirit and is started the raising of the ability of practice, emphasize Active Learning, classroom learning atmosphere is easily built in emphasis, this just has higher requirement to various educational experimentation equipment, wish that the phenomenon show can be more directly perceived, clear,, cost simple to operate to equipment requirement etc.
In the Middle School Physics study course, in " magnetic field " chapter, the knowledge point of Ampère force is the most important thing in physics subject always.This just has higher requirement again to experiment shows.For the teaching aid of left-hand rule checking, what continue to use at present is the combination of horsehoe magnet and electrified wire or hot-wire coil always.Its phenomenon is simple, can not Continuous Observation, and be not suitable for large-scale student viewing, and connection and the combination of each a plurality of parts of action need.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of rotary left-hand rule demonstration instrument for teaching.Simple in structure, easy to operate, visual strong, be applicable to senior middle school's Middle School Physics study course teaching.
The utility model is achieved through the following technical solutions: a kind of rotary left-hand rule demonstration instrument for teaching of the present utility model, described demonstrator comprises the conversion power supply, circular ringshaped magnet, wire, little copper sheet, iron nail, large copper sheet and wooden unit, transforming power supply is connected in an end on large copper sheet by wire, large copper sheet is wrapped in the side of circular ringshaped magnet, wooden unit is stuck in circular ringshaped magnet, iron nail is inserted on wooden unit, little copper sheet one end string is on the top of iron nail, the edge close contact of the other end and large copper sheet, wire is connected in the other end on iron nail, access transforms power supply again.
Further technical scheme, described conversion power supply changes into 36V voltage by 220V voltage, described demonstrator can transform in power supply 1 circuit and just connect and reversal connection at 36V, can change direction of current thus, cause the change of sense of rotation, be conducive to probe into the stressing conditions of the electrified wire that is present in the different directions in magnetic field.
The beneficial effects of the utility model are: adopted described technical scheme, the user can pass through simple connection, switch is closed just can create the effect of electrical conductor stressed Ampère force in magnetic field, total course demonstration instrument before uses convenient, operate simplyr, phenomenon is more directly perceived.
The accompanying drawing explanation
In order to be easy to explanation, the utility model is described in detail by following specific embodiment and accompanying drawing.
Fig. 1 is the structural representation of a kind of rotary left-hand rule demonstration instrument for teaching of the present utility model;
Fig. 2 is the vertical view of a kind of rotary left-hand rule demonstration instrument for teaching right half part of the present utility model.
Embodiment
As depicted in figs. 1 and 2, a kind of rotary left-hand rule demonstration instrument for teaching of the present utility model, described demonstrator comprises conversion power supply 1, circular ringshaped magnet 2, wire 3, little copper sheet 4, iron nail 5, large copper sheet 6 and wooden unit 7, transforming power supply 1 is connected in an end on large copper sheet 6 by wire 3, large copper sheet 6 is wrapped in the side of circular ringshaped magnet 2, wooden unit 7 is stuck in circular ringshaped magnet 2, iron nail 5 is inserted on wooden unit 7, little copper sheet 4 one end strings are on the top of iron nail 5, the edge close contact of the other end and large copper sheet 6, wire 3 is connected in the other end on iron nail 5, access transforms power supply 1 again, the utility model has adopted circular ringshaped magnet 2 structures, utilize circular with neither head nor tail characteristic condition, large copper sheet 6 is in continuous magnetic field all the time, as long as switch on power, will be subject to the impact of Ampère force and rotate, increased motion amplitude, make phenomenon more obviously directly perceived.
A kind of optimal way of the present utility model, described conversion power supply 1 changes into 36V voltage by 220V voltage.
Described little copper sheet 4 is because its light, little characteristic work as turn-on current, while being subject to again simultaneously the function influence of the circular ringshaped magnet 2 in below, is subject to after the Ampère force effect significantly rotating in fixed axis motion, and coil micro-pendulum phenomenon in classroom is more obvious before.
The above, be only embodiment of the present utility model, but protection domain of the present utility model is not limited to this, and any variation or replacement of expecting without creative work, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
