Abstract
The utility model discloses a current magnetic effect experimental instrument and relates to the technical field of experimental instruments. The current magnetic effect experimental instrument is characterized by comprising a base, a steel needle, a small magnetic needle, a copper wire and a power line, wherein the steel needle is vertically arranged on the base; the upper end of the steel needle is connected with the small magnetic needle; the copper wire passes through the upper part of the small magnetic needle, and a first connecting point and a second connecting point are formed between the copper wire and the base; the first connecting point and the second connecting point are respectively positioned on two sides of the small magnetic needle; and two ends of the copper wire are respectively connected with the power line. The current magnetic effect experimental instrument is simple in structure, easy to manufacture, easy to operate and obvious and intuitive in experimental phenomenon, clearly and understandably demonstrates the physical principle and can serve as a teaching instrument or an extracurricular small experimental instrument for students.
Description
Technical field
The utility model relates to the experimental apparatus technical field, is specifically related to a kind of magnetic effect of electric current experiment instrument.
Background technology
The magnetic field of electric current be a kind of objective, can not touch but the particular matter form of outwardness; The outwardness of only showing current field with the Physical Experiment of visual pattern, the influence that just can make student's ability visual pattern ground observe, understand and grasp the existence of this " object " and changed by correlated condition.In traditional teaching, be the magnetic effect situation of demonstration electric current, often adopt to be connected coil (electromagnet), switch with power supply; Place small magnetic needle near the coil; The energising back is observed the experiment of the variation of small magnetic needle and is carried out teaching demonstration, this experimental technique and coupling arrangement, and phenomenon is not obvious; Trivial operations, experimental provision also can't oneself be made.
The utility model content
The utility model technical matters to be solved be to provide a kind of simple in structure, be prone to make, the obvious magnetic effect of electric current experiment instrument intuitively of easy to operate, experimental phenomena.
The utility model technical matters to be solved adopts following technical scheme to realize:
The magnetic effect of electric current experiment instrument; It is characterized in that: comprise base, draw point, small magnetic needle, copper wire and power lead; Wherein draw point vertically is located on the base, and the upper end of draw point connects small magnetic needle, is provided with first tie point and second tie point between the top of said copper wire process small magnetic needle and the base; Said first tie point and second tie point lay respectively at the both sides of small magnetic needle, and the two ends of said copper wire also are connected to power lead respectively.
Said base is a plastic construction.
After the energized, small magnetic needle deflection, with after the power positive cathode transposing, the then reverse deflection of small magnetic needle, experimental phenomena is obviously directly perceived, clear understandable with the physical principle demonstration.
The beneficial effect of the utility model is: the utility model is simple in structure, be prone to make, easy to operate, experimental phenomena is obviously directly perceived, clear understandable with the physical principle demonstration can be used as instruments used for education and uses, and also can be used as the extracurricular little experimental apparatus of student.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein: 1, base; 2, draw point; 3, copper wire; 4, small magnetic needle; 5, power lead; 6, first tie point; 7, second tie point.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1; The magnetic effect of electric current experiment instrument comprises plastic feet 1, draw point 2, small magnetic needle 4, copper wire 3 and power lead 5, and wherein draw point 2 one ends are located on the base 1; The other end of draw point 2 connects small magnetic needle 4; Be provided with the both sides that first tie point 6 and second tie point, 7, the first tie points 6 and second tie point 7 lay respectively at small magnetic needle 4 between the top of copper wire 3 process small magnetic needles 4 and the base 1, the two ends of copper wire 3 also are connected to power lead 5 respectively.
After the energized, small magnetic needle 4 deflections, with after the power positive cathode transposing, 4 reverse deflections of small magnetic needle, experimental phenomena is obviously directly perceived, clear understandable with the physical principle demonstration.
More than show and described ultimate principle of the utility model and the advantage of principal character and the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the instructions that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
