SOL 2.2 - Magnets - investigate and understand that natural and artificial magnets have certain characteristics and attract specific types of metals
| What can magnets do? | ||
| Magnets contain iron
and produce a magnetic field around them that pushes or pulls on other materials
containing iron or nickel.
|
||
| What kinds of objects do magnets affect? | ||
| Magnets push (repel) or
pull (attract) metals. If they do
not contain iron or nickel (are non-metal), they cannot be pushed or pulled by a
magnet.
|
||
| How do magnets react to other magnets? | ||
| A magnet has two ends
called positive and negative
poles. Located at the poles of
a magnet is where the magnet’s pull is the strongest. Magnets will react with each other.
Opposite ends of two magnets—the positive pole of one and the negative
pole of the other—attract each other, and the positive ends of one and the
positive end of another—or two negative poles—repel each other.
|
||
| What is a magnetic compass and what does it do? | ||
| The two ends of the
earth—the North Pole and the South Pole—have opposite magnetic fields.
A compass has an iron-containing needle or pointer that is allowed to
swing freely and is attracted to the North Pole by aligning with the earth’s
magnetic field. A compass can help
us find north, south, east, and west directions by turning it so the needle
points to the “north” on the compass.
