Magnets Review

You cut a permanent magnet into molecules. Which best describes what you will have?

• Each molecule is a temporary magnet

• Each molecule is a permanent magnet

• Each molecule will have a North Pole, but no South Pole

• Each molecule is no longer a magnet

Read each statement. Determine if the statement supports the claim that magnets have a magnetic field or does not support the claim.

Groups:

(a) Evidence of Magnetic Fields

,

(b) Not Evidence of Magnetic Fields

• My magnet would not stick to the aluminum door handle

• The paperclip jumped to the magnet

• The iron filings on the paper plate made a pattern when placed above a magnet

• I pushed the magnets toward each other, but they would not touch
