In the present embodiment one, tongue tube building block 2 and inductance coil building block 3 parallel being plugged on the insulated chassis, circulator is installed between tongue tube building block 2 and the inductance coil building block 3; And described circulator is a spinning top 4; Described spinning top 4 comprises a gimbal and gyrorotor, and gimbal is arranged between tongue tube building block 2 and the inductance coil building block 3; Gyrorotor is arranged on the gimbal by its central shaft, and two semicircles about gyrorotor is divided into are symmetrically installed with permanent magnet 6 of the same size two semicircle inside.
Two semicircles of gyrorotor are made as respectively A semicircle and B semicircle, and when with external force switch gyrorotor, when the permanent magnet 6 of A semicircle went to from the nearest position of tongue tube, the permanent magnet 6 of B semicircle was also just in time aimed at inductance coil.After tongue tube is subjected to magnetic force induction, two pole piece adhesive conductings of its inside, triode is also with regard to conducting; Flow through the electric current of triode by behind the inductance coil, inductance coil produces the magnetic field that the permanent magnet 6 with gyrorotor repels mutually, the permanent magnet 6 of gyrorotor is subject to magnetic repulsion, gyrorotor is promoted rapidly to rotate, behind the position of the permanent magnet whiz tongue tube of A semicircle, the pole piece of tongue tube flicks, and triode stops conducting; When the permanent magnet 6 of B semicircle rotated to the tongue tube position, the permanent magnet 6 of A semicircle was also just in time aimed at inductance coil, and tongue tube is adhesive again, and triode is conducting again, and inductance coil again produces and repels magnetic field with rotor promotion rotation; Go round and begin again, spinning top 4 is constantly rotated by magnetic force moving like this.
Behind the plugged, spinning top 4 is ceaselessly rotation on gimbal, but is not by the motor drives gyrorotor, and produces the magnetic field of repelling each other with permanent magnet by inductance coil, by the magnetic repulsion drive rotor, realizes the electromagnetism cross complaint; Also observe very intuitively simultaneously the magnetic force property phenomenon, the present invention reaches the effect of joy religion unification.
Further, described second servo loop also comprises above-mentioned triode building block 1 and light emitting diode building block, the input of described triode building block 1 is connected with power supply building block 7, the base stage of triode building block 1 is connected with tongue tube building block 2, the output of triode building block 1 is connected with an end of light emitting diode building block, and the other end of light emitting diode building block is connected with the negative pole of power supply building block 7.
Two pole piece adhesive conductings after tongue tube is subjected to magnetic force induction, triode are also with regard to conducting, and the light emitting diode of gyrorotor below is shinny; When the pole piece of tongue tube flicks, triode stops conducting, and light emitting diode extinguishes; When permanent magnet 6 rotated to the tongue tube position, tongue tube is adhesive again again, and triode is conducting again, and light emitting diode is also lighted again; Go round and begin again, spinning top 4 is constantly rotated by magnetic force moving like this, and light emitting diode is along with constantly glittering.
In the present embodiment one of invention, this electronic building blocks also comprises current-limiting resistance building block 9 and switch building block 8, and described current-limiting resistance building block 9 is connected in series with tongue tube building block 2, and switch building block 8 is connected in series with power supply building block 7.The electric current of tongue tube is less, and the damage that two each closures of pole piece of tongue tube cause is just less, and the life-span of use is just longer.Under normal circumstances, current-limiting resistance is so that the size of current of passing through this tongue tube below 1mA, has so just prolonged the service life of tongue tube widely.
Embodiment two.
The operation principle of embodiment two is consistent with the operation principle of embodiment one, both differences are that tongue tube building block 2 is different from setting position and the circulator of inductance coil building block 3, therefore no longer specifically set forth the operation principle of circuit theory and electronic building blocks in embodiment two.
Be that the magnetoelectricity cross complaint of the present embodiment two drives electronic building blocks such as Fig. 6, electronic building blocks construction diagrams shown in Figure 7, its corresponding circuit diagram is Fig. 5; As seen from the figure tongue tube building block 2 and the 3 stacked settings of inductance coil building block of the present embodiment two.If tongue tube building block 2 is plugged on the top of inductance coil building block 3, in theory also be fine, because the magnetic field of inductance coil is not very large, if inductance coil below words, motive force to circulator is smaller, even can't utilize inertia so that circulator is rotated further under the effect that is not subjected to magnetic repulsion.As preferably, described inductance coil building block 3 is plugged on the top of tongue tube building block 2, and circulator is installed in the top of inductance coil building block 3, and the magnetic field that inductance coil produces is more strengthened, and is larger to the magnetic repulsion of circulator.
In embodiments of the invention two, described circulator is rotating windmill 5, described rotating windmill 5 comprises windmill support and the rotary body with three fan leafs, and described rotary body vertically is suspended on the windmill support by axle sleeve, and the end of each fan leaf respectively is installed with a permanent magnet 6.
As shown in Figure 6 and Figure 7, this rotating windmill 5 is provided with three fan leafs, respectively be installed with a permanent magnet 6 in the end of each fan leaf, by axle sleeve vertical the hanging of fan leaf is placed on the windmill support, tongue tube building block 2 and inductance coil building block 3 are intersected assembly unit under rotating windmill 5, after tongue tube and current-limiting resistance were connected in series, the base stage with the PNP triode linked to each other again; Inductance coil then is connected with the output of PNP triode; Three fan leafs of rotating windmill 5 are respectively A fan leaf, B fan leaf and C fan leaf, when using external force switch fan leaf, when the A fan leaf goes to top with tongue tube, after tongue tube is subject to the magnetic force induction of permanent magnet 6 of A fan leaf end, two pole piece adhesive conductings of tongue tube, triode is also with regard to conducting, flow through the electric current of triode by behind the inductance coil, inductance coil produces the magnetic field that the permanent magnet 6 with the fan leaf end repels mutually, and fan leaf is subject to magnetic repulsion and is promoted rapidly Windmill rotary.Behind A fan leaf whiz tongue tube position, the tongue tube pole piece flicks, and triode stops conducting; Again when B fan leaf or C fan leaf rotate to the top of tongue tube, also be that same principle produces magnetic repulsion and promotes Windmill rotary; Go round and begin again like this, windmill is constantly rotated by magnetic force moving.
Above content is preferred embodiment of the present invention only, for those of ordinary skill in the art, according to thought of the present invention, all will change in specific embodiments and applications, and this description should not be construed as limitation of the present invention.
