13. Why does your hair stand up on your head
when you touch a Van de Graaff generator.
If a person scuffs their feet on
the carpet they pick up extra
electrons and have a negative
charge. If you touch a person or
a doorknob, the electrons jump
to that object. The movement of
electrons feel like a tiny shock.

- -
Magnets have “poles” or
“ends” that are charged
with either a positive or a
negative charges also.
These poles are called the
north pole and the south
pole. “Like” poles (same
charge) will repel one
another. “Opposite” poles
will attract each other.
-
A Van de Graaff generator will release
negative charges to your body when you
touch it. ALL your hairs on your head
become negatively charged Since al the
hairs are the same charge they move
away from each other. This causes your
hair to stand up on your head.
