[Application 1]Static machine 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. [Application 2]Itself can also be used for a series of experiments, such as electrostatic induction, spark discharge, point discharge and capacitor capacitance change and so on. [Working Principle]This generator uses induction effect to produce static, when two electrophorus spin, the charged sy, especially ball part on discharge fork equipped with insulated handle, will gather a lot different electric charge. [Features]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.Improved static generating performance, it can generate static even in humid climate and rainy day.
