Charging by Induction

Charging by Induction. Charging by Induction: Temporarily. When a charged object is brought close to, but not touching, a neutral object, the electrons in the neutral object move either away from or toward the charged object.

  1. Charging by Induction

  2. Charging by Induction: Temporarily When a charged object is brought close to, but not touching, a neutral object, the electrons in the neutral object move either away from or toward the charged object. When electrons move within an object because of a nearby charged object, it is called induced charge separation. induced charge separation charging by induction

  3. Charging by Induction: Temporarily

  4. Charging by Induction: Temporarily Once the charged object is moved away, the electrons in the neutral object return to their original positions.

  5. You can permanently charge an object using induction. To do this, you need to ground the neutral object. Charging by Induction: Permanently

  6. Charging by Induction: Permanently _ _ _ _ A negatively charged object is placed near a neutral object, causing the electrons to move.

  7. Charging by Induction: Permanently _ _ _ _ The neutral object is grounded, allowing the repelled electrons in the neutral object to escape to the ground. The neutral object loses electrons.

  8. Charging by Induction: Permanently _ _ _ _ The ground is removed, leaving the ball with a positive charge.

  9. If electrons move from the neutral object through the wire to the ground (object loses electrons), the object becomes positively charged. If electrons move from the ground through the wire toward the object (object gains electrons), the object becomes negatively charged. Charging by Induction: Permanently

  11. Applications of Static Electricity

  12. Note: Charging by Induction This method of charging objects involves no contact between a charged object and a neutral object, and grounding is used.

  13. Note: Charging by Induction 1. Negative Neutral

  14. Note: Charging by Induction 1. Negative e- Neutral

  15. Note: Charging by Induction 1. A negatively charged rod is placed near a neutral object. The excess electrons in the rod repel the _____________ in the object making them move as far away from the rod as possible. This shifting of electrons makes one side of the object __________________ and the other side _________________ (however, the object is still neutral). This is called _____________________________. electrons positive negative induced charge separation

  17. Note: Charging by Induction • 2. • If the neutral object is grounded, the repelled electrons move from the ____________ to the ___________ (the object _________ electrons). object ground loses

  18. Note: Charging by Induction 3. Negative Positive

  19. Note: Charging by Induction • 3. • When the ground is removed, the object is left with a _____________ charge (because it _________ electrons to the ground). positive lost

  20. Note: Charging by Induction *** When objects are permanently charged by induction, the induced charge is always ______________ that of the charged object. opposite
