Description
Technical field
The present invention relates to a kind of popular science knowledge apparatus for demonstrating, the apparatus for demonstrating of alternation energization solenoid magnetic observation specifically.
Background technology
Second physics of senior middle school (Senior Two) chapter 15 first segment (P170): we recognize that magnet or electric current produce magnetic field in its surrounding space, and magnetic field is to magnetic pole that is in its inside or the effect that electric current has magnetic field force.Like this, we have obtained unified understanding to the interaction between magnetic pole and the magnetic pole, between magnetic pole and the electric current, between electric current and the electric current, and all these interactions are all transmitted by magnetic field.
Second physics of senior middle school (Senior Two) chapter 15 first segment (P170): small magnetic needle is placed in the magnetic field of magnet or electric current, small magnetic needle not necessarily points to North and South direction, and points to other some directions because of magnetic field force induced effect when its two poles of the earth are static.Difference in magnetic field, the direction of indication was general and inequality when small magnetic needle was static.This statement of facts, magnetic field are directive.Physics regulation, any point in magnetic field, the direction that the small magnetic needle arctic is stressed, that is the direction of small magnetic needle arctic indication when static are exactly the magnetic direction of that.
Second physics of senior middle school (Senior Two) chapter 15 first segment (P170): the direction of straight line current can be judged with Ampere's law (also being right-hand screw rule) with the relation between its magnetic induction line direction: hold lead with the right hand, allow the direction of the thumb indication that stretches with the sense of current unanimity, crooked four directions that refer to indications be exactly magnetic induction line around direction.
Summary of the invention
The purpose of this utility model is the apparatus for demonstrating of a kind of alternation energization solenoid magnetic of design.
The concrete structure design proposal is as follows:
The apparatus for demonstrating of alternation energization solenoid magnetic, structure comprises Demonstration table and solenoid, level is provided with needle on Demonstration table, around needle, be evenly equipped with three solenoids, the equal correspondence of each solenoid is provided with switch knob and conversion knob, on Demonstration table, also be provided with rotary handle, rotary handle is connected with each conversion knob by lead, on Demonstration table, also be provided with starting switch, solenoid, starting switch, switch knob, conversion knob and rotary handle connect into the circuit that meets the electricity rule by lead, and three solenoids are triangularly arranged around needle.
Useful technique effect of the present utility model is embodied in following aspect:
The utility model can be demonstrated the magnetic of alternation energization solenoid visual in imagely, be convenient to the understanding of student's intensification to energization solenoid magnetic, this showpiece also can be used as the motor principle apparatus for demonstrating simultaneously, can be used for science popularization venue, mobile science and technology center, as the science popularization showpiece, test product as a kind of aided education that alternation energization solenoid magnetic is observed.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a needle part enlarged drawing of the present utility model.
Embodiment
The utility model both can three people be operated, and also can a people operate, and below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment:
Embodiment 1:
The apparatus for demonstrating of alternation energization solenoid magnetic, structure comprises Demonstration table and solenoid 1, level is provided with needle 2 (see figure 2)s on Demonstration table, around needle, be evenly equipped with three solenoid 1 (see figure 1)s, each solenoid 1 equal correspondence is provided with switch knob 4 and conversion knob 5, on Demonstration table, also be provided with rotary handle 6, rotary handle 6 is connected with each conversion knob 5 by lead, on Demonstration table, also be provided with starting switch 3, solenoid 1, starting switch 3 switch knobs 4, conversion knob 5 and rotary handle 6 connect into the circuit that meets the electricity rule by lead, and described three solenoids 1 are triangularly arranged around needle 2.
When three people operated: three people were transferred to position A to own locational conversion knob 5 earlier, press starting switch 3, three people then and rotate switch knob 4 in order successively, observe the needle 2 rotation situations of center.When three people rotated switch knob 4 by opposite order, needle 2 also can reverse rotation.
Embodiment 2:
When a people operates: three conversion knobs 5 all are transferred to position B, and at this moment an end of three coils will be connected in a bit, rotary handle 6, and such three solenoids are energized successively, the needle 2 rotation situations of observing the center.When pressing opposite order rotary handle 6, needle 2 also can reverse rotation.
