Homework Help: Charging by Induction

  1. Oct 22, 2011 #1
    This isn't a homework question as such, but according to my physics book in electricity it is always the negative (electrons) charge that move. Is it possible to charge something negatively via induction?
    I mean the last step in the process is earthing the object, if you earth it, do positive charges move?

    'Yes' to the first question and 'no' to the second.

    So how do you charge negatively? By "adding" negative charges?
