Abstract
The utility model discloses an electromagnetic induction physical phenomenon tester, which comprises a base for fixing and supporting, a supporting rod fixed on the base and a crossbeam fixed on the top of the supporting rod, and is characterized in that a plurality of U-shaped magnets with upward openings are arranged on the base; a conductor rod is arranged above the openings of the U-shaped magnets; two ends of the conductor rod are connected with the crossbeam through a spring; two ends of the conductor rod are connected with a microammeter through the conductor rod; the like magnetic poles of the U-shaped magnets are positioned on the same side; and two conductor bodies are respectively connected with positive and negative binding posts of the microammeter. The conductor rod is matched with the U-shaped magnets, continuous motion of the conductor rod is guaranteed through the spring, and continuous magnetic induction line cutting motion of the conductor rod is effectively realized; and moreover, the swing of a pointer of the microammeter is observed, the electromagnetic induction phenomenon can be effectively observed and understood, and teaching of teachers and learning of students are convenient.
Description
Technical field
The utility model relates to a kind of electromagnetic induction physical phenomenon test instrument, in particular, relates in particular to a kind of intuitively face of land and is just going out the electromagnetic induction physical phenomenon test instrument that transforms between mechanical energy-magnetic energy-electric energy.
Background technology
For getting electromagnetism perception phenomenon in the physical teaching course, be to learn electromagnetic basis from now on well, also be to make much of the important experimental that mechanical energy transforms to electric energy.Also do not have now a kind of instruments used for education can mechanical energy to the conversion of electric energy from minute embody so that make many students deep understanding and cognition arranged to it.For the instruments used for education with Comprehensive Experiment, it can complete many Physical Experiments undoubtedly, but all can not be visually the conversion between mechanical energy-magnetic energy-electric energy intuitively, characterize visually.
Summary of the invention
The utility model has overcome the shortcoming of above-mentioned technical matters, provides a kind of intuitively face of land just going out the electromagnetic induction physical phenomenon test instrument that transforms between mechanical energy-magnetic energy-electric energy.
For realizing above-mentioned purpose, the utility model has adopted following technical scheme:
The electromagnetic induction physical phenomenon test instrument of the utility model; The base of fixing and supporting role, the crossbeam that is fixed in the support bar on the base and is fixed in supporting bar top have been comprised; Its special feature is: said base is provided with a plurality of openings U magnet up; The top of U magnet opening is provided with conductor rods, and the two ends of this conductor rods all are connected with crossbeam through spring; The two ends of said conductor rods are connected with microampere meter through wire body; The magnetic pole of the same name of said U magnet is in the same side, and two wire bodies are connected with the positive and negative binding post of microampere meter respectively.
Base, support bar and crossbeam have constituted fixed support, and conductor rods passes through two spring suspensions at the two ends of crossbeam, so that realize swinging up and down of spring.Because conductor rods is positioned at the top of U magnet opening; Conductor rods will be done the cutting magnetic induction line motion in the process of motion; Two ends at conductor rods will produce voltage, because conductor rods, wire body and microampere meter have constituted the galvanic circle, therefore will produce induction current; Can confirm through the beat of pointer of observing microampere meter.Like this, electromagnetic induction phenomenon has just showed incisively and vividly.
The electromagnetic induction physical phenomenon test instrument of the utility model, the two ends of said conductor rods all are hung with counterweight.Through increasing counterweight, can increase the amplitude of fluctuation and the number of times of conductor rods, help producing lasting induction current.
The electromagnetic induction physical phenomenon test instrument of the utility model, the quantity of said U magnet is 5.A plurality of U magnets are set, help producing bigger electric current.
The beneficial effect of the utility model is: the utility model is through cooperating conductor rods and U magnet; And the continuous motion that guarantees conductor rods with spring; Realized the cutting magnetic induction line motion that conductor rods is continuous effectively; Through observing the beat of pointer of microampere meter, can observe effectively and understand electromagnetic induction phenomenon, be convenient to teachers ' teaching and student and learn.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1 base, 2 support bars, 3 crossbeams, 4 springs, 5U shape magnet, 6 conductor rods, 7 counterweights, 8 wire bodies, 9 microampere meters.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
As shown in Figure 1, provided the structural drawing of the electromagnetic induction physical phenomenon test instrument of the utility model, it comprises base 1, support bar 2, crossbeam 3, spring 4, U magnet 5, conductor rods 6, counterweight 7, wire body 8, microampere meter 9; 1 fixing and supporting role of shown base, crossbeam 3 is fixed on the base 1 through support bar 2.On base 1, conductor rods 6 is positioned at the top of U magnet 5 openings with opening form fix up for four U magnets 5, and the lower ends of the two ends of conductor rods 6 and two springs 4 connects, and the upper end of two springs 4 is fixed on the crossbeam 3.Two groups of counterweights 7 are suspended on the two ends of conductor rods 6 respectively, and two wire bodies 8 are used for the two ends of bonding conductor bar 6 and the both positive and negative polarity of microampere meter 9.Like this, in the process of using, through pressing down conductor rods 6; Make its lower position that moves to the U-lag of U magnet 6, decontrol arm, conductor rods 6 will move up and down under the effect of spring 4 and counterweight 7; In the process of motion, can cutting magnetic induction line.The electric current that produces will pass through microampere meter 9, makes the pointer of microampere meter 9 swing.
The utility model is through cooperating conductor rods and U magnet; And the continuous motion that guarantees conductor rods with spring; Realized the cutting magnetic induction line motion that conductor rods is continuous effectively; Through observing the beat of pointer of microampere meter, can observe effectively and understand electromagnetic induction phenomenon, be convenient to teachers ' teaching and student and learn.
