Abstract
The utility model discloses a toy capable of being used as an electromagnetic induction demonstrator, which relates to the technical field of teaching aids. The toy consists of an organic glass tube, a magnet, a diode and coils, wherein two wire clamping grooves are arranged at the two ends of a small organic glass tube, and a plurality of coils are wound on the small organic glass tube; the two end points of the coils are respectively fixed on the wire clamping grooves at the two ends of the small organic glass tube through a wire, and is welded with a light-emitting diode (LED); a large organic glass tube is sheathed outside the small organic glass tube; the LED, the coils and the wire are all arranged between the small organic glass tube and the large organic glass tube; one ends of the small organic glass tube and the large organic glass tube are welded on a fixed plug, the other ends are welded together and form a nut so as to be fixed through the matched screw plug; and a magnet is arranged in the small organic glass tube. Compared with the prior art, the toy capable of being used as the electromagnetic induction demonstrator has the advantages that: the manufacturing material is easy to get, the demonstrator is convenient to use and easy to improve, thereby having popularization value.
Description
Technical field
The utility model relates to a kind of electromagnetic induction demonstration teaching aid, is a kind of toy electromagnetic induction demonstration device of holding concurrently specifically.
Background technology
New curricular reform requires in the physics experiments of high school teaching, outstanding students practise ability and the initiative spirit of cultivating, in first segment " generation of exchange current and the Changing Pattern " teaching material of second of existing high school physics (required adding takes as an elective course) the 17 chapter " exchange current ", do not have and make simple and easy, interesting strong experiment introducing problem, generation, the size and Orientation of demonstration alternating current in first, second and third joint of second of high school physics (required adding takes as an elective course) the 16 chapter " electromagnetic induction " do not have special demonstration instrument yet simultaneously.
The utility model content
The purpose of this utility model is the deficiency at existing teaching material, and a kind of toy electromagnetic induction demonstration device of holding concurrently is provided.
The purpose of this utility model realizes by following technological means: a kind of toy electromagnetic induction demonstration device of holding concurrently, to form by plexi-glass tubular, magnet, diode and coil, and respectively there are two cable clamping interfaces at little plexi-glass tubular two ends, twine multiturn coil above; Two end points of multiturn coil respectively by lead fixed on the cable clamping interface at little plexi-glass tubular two ends, and weld with light emitting diode; Little organic glass tube outside is with big plexi-glass tubular; Light emitting diode, multiturn coil and lead are all between little plexi-glass tubular and big plexi-glass tubular; One end of little plexi-glass tubular and big plexi-glass tubular is welded on fixedly on the stopper, and an other end welds together and forms nut, can fix by the screw stopper that is complementary with it, little plexi-glass tubular inside placement one magnet.
Compared with prior art the utlity model has following tangible advantage: this manufacturing materials is simple and easy to, easy to use, be easy to improve, intellectual and interest are merged, excite the interest that the student learns and the initiative of study, guiding student is from rising to rational thinking to the perception of observing, use knowledge analysis problem, problem-solving ability to cultivate the student, simultaneously can demonstration magnet motion speed the different and direction luminous situation of diode simultaneously not, allow the student inquire into reason, for the knowledge of study back is made place mat.Be that a kind of toy of promotional value electromagnetic induction demonstration device of holding concurrently is arranged very much.
