As the preferred version of the utility model, in the above-mentioned electromagnetism swing, said balance staff is through two copper wire connecting coils, and the copper wire of this moment is a conductor part.Said copper wire is convenient to support and is connected energising with coil.
As the preferred version of the utility model, in the above-mentioned electromagnetism swing, said conductor comprises thick copper lines and fine copper wire, and what connect balance staff and coil is thick copper lines, and what connect thick copper lines and support is fine copper wire.Said thick copper lines has increased the distance of coil to balance staff, can increase the rotation period of pendulum, is convenient to observe.
As the preferred version of the utility model, in the above-mentioned electromagnetism swing, also be provided with switch on said power supply and the lead that support is communicated with.Said switch is used to control being communicated with of power supply and support.
As the preferred version of the utility model, in the above-mentioned electromagnetism swing, said power supply, support and magnet are installed on the base.
The utility model principle is: when said balance staff was positioned on the support, balance staff was connected energising through conductor with the support that is connected with power supply, when the coil of balance staff below during in minimum point, and the conductor contact brackets that said coil connects; Thereby energized, coil produces magnetic, because the principle of homopolar-repulsion; Coil is boosted, and conductor and support disengage, and power supply is cut off; Fall again at gravity and action of inertia lower coil then, after the conductor energized, coil is boosted to another direction.
End about balance staff is exchanged the back energising,, make coil no longer swing owing to change the two poles of the earth, north and south that power positive cathode can change hot-wire coil.
In sum, owing to adopted technique scheme, the beneficial effect of the utility model is:
1, because the support of the utility model electromagnetism swing is connected the design of switching on coil through conductor; Utilize hot-wire coil can produce the principle of magnetic; Make pendulum on support, ceaselessly swing, when understanding the content of courses, excited student's interest, deepened the understanding of student electromagnetism knowledge.
2, because the utility model electromagnetism swing adopts materials such as common plank, copper wire to process; Cost is low, and manufacture craft is simple, can improve student's the ability that uses one's hands and brains effectively; And good looking appearance not only can be done teaching demonstration device but also can do toy and handicraft etc.
