Technical field
It the utility model is related to physics teaching demonstration teaching aid technical field, and in particular to a kind of ampere force presentation device.
Background technology
Ampere force is active force of the magnetic field to electric current, is to commemorate French physician ampere in research magnetic field to being powered
Contribution in terms of the effect of wire and name.Experiment shows, one section of electromotion straight wire is placed in magnetic field, when wire direction and magnetic
When field direction is vertical, the Ampere force suffered by electric current is maximum.Ampere force suffered by the conductor of energization, it is big that the size of power is proportional to electric current
Small, magnetic induction intensity and conductor length.If conductor length L, the electric current I that passes through, perpendicular to magnetic field, magnetic induction intensity B, peace
The size for training power is F=BIL.The direction of Ampere force is judged with left hand rule：Left hand is stretched out, four point to the senses of current, allow magnetic
The line of force passes through the palm of the hand, and the direction of thumb is exactly the direction of Ampere force.
In Process of Physics Teaching in Middle School, Ampere force is an important chapters and sections in electromagnetism, but in teaching material due to
Ampere force formula is comprehensively probed into without quantitative instrument directly perceived, easy, student, which can only rely on, to memorize mechanically to learn and answer
With.Current existing laboratory apparatus can only typically carry out the experiments of two kinds of situations to prove the formula of Ampere force, first, working as B and L
When constant, by changing I size, F change is observed；Second, as B and I constant, by changing L size, F change is observed
Change.Wherein F is Ampere force, and B is magnetic induction intensity, and I is current strength, and L is conductor length in magnetic field.Laboratory apparatus can only change
The two variables of I and L study the concept of power in magnetic field, and in magnetic field power change, also other factors, as magnetic induction is strong
Degree, the direction in magnetic field, existing equipment can not typically accomplish so that experiment is relatively simple, is unfavorable for extending the thinking of student.
The content of the invention
The purpose of this utility model is to be directed to deficiency of the prior art, there is provided a kind of ampere force presentation device.The ampere
Force demonstration apparatus have be easy to observation, it is easy to operate, easy to maintain the advantages of.
The purpose of this utility model is realized by following technological means：A kind of ampere force presentation device, its feature exist
In：Including bottom plate, riser, bar magnet, copper rod, photoelectric door, copper pipe, dc source and phototimer, wherein, the bar shaped
Magnet is evenly arranged on the bottom plate, two pieces of risers of the parallel installation in both ends of the bottom plate, above two pieces of risers respectively
Copper rod is installed, one end of two copper rods is connected by wire with the dc source respectively, in the front end of the bottom plate
Two photoelectric doors are fixed with, two photoelectric door is connected by signal wire with the phototimer, and the copper pipe is placed in two bronze medals
On rod.
Preferably, two positioning disks are mounted with copper pipe in the intersection of the copper pipe and riser.
Preferably, graduated scale is installed on the bottom plate.
Compared with prior art, the utility model has advantages below：(1) when demonstrating, electrical conductor copper pipe is in orbit
The phenomenon of rolling movement clearly, can show the action effect of Ampere force very well；(2) that is installed on electrical conductor copper pipe leads
Rolling to disk to copper pipe play the guiding role, and such copper pipe would not fall down from track, it is ensured that Success in Experiment；(3) it is logical
The change of the length of electric conductor can be by changing riser position adjustments, and the strong and weak change in magnetic field can be counted up to by increasing and decreasing magnet
Into the big minor adjustment of electric current can be adjusted by dc source in electrical conductor；(4) transported by measuring copper pipe between two photoelectric doors
The size of dynamic time indirect measurement Ampere force is easier.
