Electrostatic demonstration teaching implement

静电演示教具

Abstract

The utility model discloses an electrostatic demonstration teaching implement, which relates to the teaching implement technical field. The implement has an insulating swing-rod, one end of which is provided with a conducting sphere and the other end of which is provided with a counterbalance; the swing-rod is arranged on a supporting stand by an axis. When used as teaching demonstration, the utility model can resolve the deficiency of the electrostatic demonstration teaching implement, compared with prior art. The implement can be perceptible for the repellent force and attractive force between the charges in the experiment, and can demonstrate the qualitative experiment of the Coulomb Law, the electric field experiment, the electrostatic induction and electrostatic induction electrization experiment.
本实用新型公开了一种静电演示教具,涉及教学用具技术领域,它有根一端装有导电球、另一端装有平衡锤的绝缘摆杆,该绝缘摆杆通过轴装在一支架上。它用来进行教学演示时,与现有技术相比,可以解决现有的静电演示教具不足,它能让人在实验过程中感知电荷间的排斥力和吸引力,可以演示库仑定律的定性实验、电场的实验和静电感应及静电感应起电的实验。
