Textbook
Section
If an object is positively charged it will induce
electrons in the neutral object to move towards it
If an object is negatively charged it will induce
electrons in the neutral object to move away from it
After the electrons shift position, the neutral object will be
attracted to the charged object
the neutral object doesn't gain or loose electrons
Charging Objects Permanently by
Induction
We can do this by grounding the object that's being
charged
Example: Pith Ball! Fancy Smartboard drawing time!
