Features: _x000D_ This generator uses induction effect to produce static, when two electrophorus spin, the charged system, especially ball part on discharge fork equipped with insulated handle, will gather a lot different electric charge. _x000D_ The conductive layer of conductive plate is coated with conductive material, coating is firm, durable and overcomes the shortcomings that aluminum foil is easy to fall off. _x000D_ Improved static generating performance, it can generate static even in humid climate and rainy day. _x000D_ It is used in the experiment of electrostatics to get a lot of charge and high voltage about tens of thousands of volts), in combination with other instruments for experiments about charge distribution on conductor surface, power line or electrostatic field, point discharge and discharge of vacuum tube. _x000D_ Itself can also be used for a series of experiments, such as electrostatic induction, spark discharge, point discharge and capacitor (refer to the Leyden jar on generator) capacitance change and so on. _x000D_ _x000D_ Specifications: _x000D_ Model: 23008 _x000D_ Material: Metal _x000D_ Size: Approx. 33.5 x 29 x 19.5cm/13.2 x 11.4 x 7.7in _x000D_ Package Weight: 1.5kg(approx.) _x000D_ _x000D_ _x000D_ Package Includes: _x000D_ 1 x Static Machine
