  1. Charging a Neutral Object by Conduction or Induction

  2. Charging by Conduction • Positive Object before touch Neutral Electroscope

  3. Charging by Conduction • Positive Object during touch Electrons move upward and onto the charged rod. Electroscope now has more + than -.

  4. Charging by Conduction • Positive Object after touch Both the object and the electroscope have the same amount of positive charge.

  5. Charging by Conduction • Negative Object before touch Neutral Electroscope

  6. Charging by Conduction • Negative Object during touch Electrons move from charged object onto electroscope. Electroscope now has more – than +.

  7. Charging by Conduction • Negative Object after touch Both the object and the electroscope have the same amount of negative charge.

  8. Charging by Induction • Positive Object before touch Neutral Object Neutral Electroscope

  9. Charging by Induction • Positive Object during flyby Neutral Object Electrons move nearer to the strong positive object. Electroscope appears to be charged because of this shift.

  10. Charging by Induction • Positive Object during touch of neutral object The neutral object accepts the higher concentration of electrons from the top of the electroscope.

  11. Charging by Induction • Positive Object after The original object has the same charge, the electroscope is now positive, and the neutral object has a negative charge.

  12. Charging by Induction • Negative Object before flyby Neutral Object Neutral Electroscope

  13. Charging by Induction • Negative Object during flyby Neutral Object Electrons move further away from the strong negative object. Electroscope appears to be charged because of this shift.

  14. Charging by Induction • Negative Object during touch of neutral object Neutral object donates some of it’s electrons to the positive top of the electroscope. The neutral object now has a excess positive charge.

  15. Charging by Induction • Negative Object after Original negative object has the same charge, electroscope has excess negative, and neutral object has become positive by losing electrons.
