  • could you do that permenantly with an electret?

  • @theonelinerkid No. The pendulum transfers charge to the ground and consumes energy, and both must come from somewhere. You can use an electret as the base for the electrophorus, probably.

  • The current that flows through the pendulum to the fixed plate is maximum when the charged plate of the electrophorus is moving towards the plate. After the plates touch the charge returns to the earth through the pendulum, but at a smaller rate.

  • Esse disco branco serve para carregar o eletroforo, né? Onde consigo um? Ele é de resina? Consigo fazê-lo? Gostei muito do vídeo... Minha maior dificuldade é carregar o eletroforo.

  • É uma tampa de caixa de requeijão Catupiry. Os suportes isolantes são caixas de requeijão. Esfregue a tampa no cabelo para eletrizar. Tem que estar tudo muito seco. Use um secador de cabelo para secar, se necessário.
