​

What is Magnetism?

Magnetism is an invisible force or field caused by the unique properties of certain materials. Magnets can push or pull things.

Multiple Choice

What do magnets do?

• Push or pull things

• Make things bigger or smaller

• Make things change color

Things magnets CAN pull

• Things made of metal

• Contain iron

• What things have you noticed are attracted to magnets?

Multiple Choice

What kinds of things will a magnet attract, or pull on?

Multiple Select

How is plant earth like a magnet?

• They both have oceans and land

Multiple Choice

Which items would be attracted by magnetic pull?

• Phineas, a piece of hair, a banana

Magnets can make electricity!

You can put a metal wire near a magnet (so the wire is inside the magnetic field). Move the wire or move the magnet so the magnetic field inside the wire fluctuates and electricity will flow through the wire. Keep moving the wire or magnet and you'll make electricity continually.

Opposites

Magnetic Poles

When two like-poles point together, the arrows from the two magnets point in OPPOSITE directions and the field lines cannot join up. So the magnets will push apart
