1. What is a magnet? A magnet is any material
that attracts iron and materials that contain
iron.
2. What are three properties of a magnet? A
magnet attracts materials that contain iron,
attracts or repels other magnets, and has
one pole that points north when allowed to
swing freely.
3. What will happen to a bar magnet that is
allowed to swing freely? The bar magnet
will align itself in a north-south direction.
4. What area of a magnet has the strongest
magnetic effect? A magnet’s poles have the
strongest magnetic effect.

5. How does a magnet’s north pole behave
when brought near another north pole?
Near a magnet’s south pole? Two
magnetic north poles repel each other. A
magnetic north and a magnetic south
pole attract each other.
6. How can the behavior of two magnets
show the presence of a magnetic force?
When unlike magnetic poles of two
magnets are brought near one another, a
force of attraction will tend to pull them
together. When magnetic poles that are
alike are brought near each other, a force
of repulsion will tend to push them apart.

7. What is a magnetic
field? A magnetic field
is the area of magnetic
force around a magnet.
8. Look at Figure. What is
the shape of the
magnetic field? The
shape of a magnetic
field resembles two
side-by-side ovals, with
the bar magnet lying
along the long sides of
the ovals where they
contact each other.
