Features: Principle: Static electricity generator uses induction effect to generate static electricity, when two electric coils rotate, the charged system, the spherical part on the discharge fork equipped with insulated handle, will gather a large number of different electric charges. Durable: Static machine conductive plate conductive layer coated with conductive material, the coating is firm and durable, overcoming the shortcomings of aluminum foil easy to fall off. High Performance: Electrostatic induction generator improves the performance of static electricity generation, even in humid climate and rainy days. Electrostatic Experiment: Static electricity discharger is used for electrostatic experiments to obtain a large amount of charge and high voltage (about tens of thousands of volts), combined with other instruments for charge distribution on the surfaces of conductors, power lines or electrostatic devices. Multipurpose: Static field generator can also be used for a range of experiments, such as electrostatic induction, spark discharge, point discharge and capacitor capacitance change, and etc. Specifications: Material: Synthesize Color: As The Picture Shows Package Weight: approx.800g Size: approx.26x12x30cm/10.23x4.72x11.81in Package Includes: 1Pc x Static Electricity Generator note: Please allow 1-2cm error due to manual measurement.
