Electrostatic jump ball demonstrationElectrostatic jump ball demonstration ,This is our new creative series which used for junior middle school Innovation experimental ! new beautiful design and very eash to be used.
A charged object and uncharged conductor close to each other due to charge interactions, will charge redistribution inside the conductor, dissimilar charges are attracted to the vicinity of the charged, and the same kind of charge is repelled away from the other conductor of a charged body end. This phenomenon is called electrostatic induction.
Under the action of an external electric field, the conductor of the charge in the guide Body redistribution phenomenon. This phenomenon by the British• State scientist John Compton and Swedish scientists about John • Carl • Wilke in 1753, respectively, and 1762 discovery. If the original has a negative rubber truncheon X Charge inducing charge can be called, if the conductor connected D Near charged body X, due to charges repel, unlike charges attract, so the negative charge on X in D electric field created by the free electron repulsion far stick side to D and put the same amount of positive charge left bar near the D side, the electric field strength until D is zero.
Center ball and a metal ring with a circumference of different charge, in the middle of the metal balls in an electric field is induced, ends with dissimilar charge, because of the distance and different, unbalanced forces generated by the movement.
