Content disclosed by bright book understands other advantages and effect of the utility model easily.The utility model can also be by addition
Different specific embodiments are embodied or practiced, and the various details in this specification can also be based on different viewpoints and answer
With carrying out various modifications or alterations under the spirit without departing from the utility model.It should be noted that institute in following embodiment
The diagram of offer only illustrates the basic conception of the utility model in a schematic way, in the absence of conflict, following embodiment and
Feature in embodiment can be combined with each other.
Fig. 1-Fig. 2 is please referred to, the element numbers in attached drawing respectively indicate: coil track 1, first coil 11, the second coil
12, magnetomotive train module 2, magnet module 21, power supply 22, bottom 23.
The utility model relates to a kind of for demonstrating the magnetomotive train device of magneticaction, comprising: for generating electromagnetism
Coil track 1, including joining end to end and first coil 11 that the number of turns is different and the second coil 12, the first coil 11
The number of turns be greater than the number of turns of second coil 12, the coil track 1 is arranged in a ring；For generating magnetostatic field and in coil
The magnetomotive train module 2 of shuttling movement in the same direction on track 1, including the pedestal on coil track 1 and along rail running is arranged in
23 and the power supply 22 and magnet module 21 that are arranged on pedestal 23；When device works, the pedestal 23 is placed on the second line
It powers on circle 12 and for power supply 22, the magnetostatic field that the magnet module 21 generates and the electromagnetic field that the coil track 1 generates are mutual
Phase separation, so that the pedestal 23 is along the coil track 1 shuttling movement in the same direction until power supply 22 stops power supply.
Preferably, the both ends of the first coil 11 are separately positioned on the both ends outer surface of second coil 12, and
It is fixedly connected with second coil 12；The first coil 11 is consistent with the direction of circling of second coil 12；The electricity
Source 22 is No. 5 dry cells of 1.5V；The first coil 11 is made with the second coil 12 of copper wires；The magnet module
21 be neodymium iron boron magnetic body stone；The magnet module 21 is in oblate column.
Specifically, the magnet module 21 includes the first magnet and the second magnet, first magnet and the second magnet phase
One end of same polarity and the positive and negative anodes of the power supply 22 are respectively connected with；In the present embodiment, the pole N of first magnet with it is described
The anode of power supply 22 is connected；The pole N of second magnet is connected with the cathode of the power supply 22；In various embodiments,
Structure type as described below can be set into, the pole S of first magnet is connected with the anode of the power supply 22；Described
The pole S of two magnet is connected with the cathode of the power supply 22.
In the specific manufacturing process of the present embodiment, pedestal 23 is made using the straight plank of the higher length of coefficient of friction, by copper
Matter conducting wire is around in a diameter greater than the coil track 1 of spring-like shape is made on the smooth cylindrical pipe of 21 diameter of magnet module,
The copper wires of each ring are not collided mutually.Magnet module 21 is finally adsorbed in 22 both ends of power supply, and magnetomotive train module 2 is put
On the second less coil 12 of the number of turns.
In this experiment, after pedestal 23 enters coil track 1, due to the positive and negative anodes of power supply 22 and the first magnet and the
