Simple Model of Charges in a Conductor
Effect of Approaching a Positive Charge
  • Note that the motion of the positive charges is not shown since it is quite small compared to the motion of the negative charges.
  • Note also that the charges are not drawn to scale. Negative charges are much smaller than positive charges.
  • Focus on what happens to the negative charges (the blue ones) as we move a positively charged ribbon near our block. When the charged ribbon is away, the negative charges move at random. When the charged ribbon is near, the negative charges are attracted to top while still moving randomly.
