  1. Electrostatics Charging by Induction

  2. Induction or to induce means - to make something happen without contact Charging by Induction means • transferring an electric charge from one object to another without direct contact • (the charged rod DOES NOT touch) TVO Induction 10 min: http://www.youtube.com/watch?v=o0hXYfvnND0

  3. 2 ways to charge by induction: • TEMPORARY also called Induced Charge Separation • - a slight shift of electrons producing opposite charges on two sides of an object • Example: Metal rod temporarily charged by induction • Before DuringAfter - - - - - - - - - - + + + + - - - - + + + - + - - - + + + + - - - - + + + + - - - - + + + + - - - - + + + + - - - - neutral positive negative neutral

  4. 2 ways to charge by induction: 2) PERMANENT - using a ground (ex. your hand, conducting wire attached to a water tap) to transfer charges into or out of the object Example: Metal rod permanently charged by induction Before DuringAfter - - - - - - - - - - + + + + - - - - + + + - + - - - + + + + - - + + + + - - + + + + - - - - + + + + - - - - e- neutral permanent positive charge ground

  5. Home Fun : • Finish any questions from the lab sheet • Read page 408 and answer #3, 4 and 5 on page 409.
