What is Induction?

1
What is Induction?

• Charging by induction is where a charged object
  causes electrons to move inside another object,
  without them touching.
• No charges move from one object to the other
• The other object ends up being polarized

2
Neutral (equal numbers of and charges)
Positively Charged

• As the positive object moves toward the neutral
  one, the positive object attracts the electrons
  in the neutral one.

3
Neutral (equal numbers of and charges)
Positively Charged

• As the positive object moves toward the neutral
  one, the positive object attracts the electrons
  in the neutral one.
• The positive object induced the electrons to
  move.
• The neutral object is now polarized.

Neutral (equal numbers of and charges)
Positively Charged

• As the positive object moves toward the neutral
  one, the positive object attracts the electrons
  in the neutral one.
• The positive object induced the electrons to
  move.
• The neutral object is now polarized.

What is Conduction?

• Conduction is the process where a charge is
  shared though direct contact.
• Like spreading the love through a hug
• awwwwwww

6
Neutral (equal numbers of and charges)
Positively Charged

• When the objects touch (or get really close)
  electrons move from one object onto the other

7
Neutral (equal numbers of and charges)
Positively Charged

• When the objects touch (or get really close)
  electrons move from one object onto the other
• The two objects share the charge equally

8
Charging by friction

• Two insulators become charged when rubbing
  together because electrons are transferred from
  one item to another.
• An example of this is rubbing a balloon against
  your hair.
