The spacing of the field lines:

• is greatest near the poles

• indicates the strength of the magnetic field

• is the same everywhere around the magnet

• indicates the direction of the magnetic field

• is smallest far away from the poles

A magnetic field line:

• represents the direction and force of the magnetic field

• represents the direction of the magnetic field

• points away from the south pole and toward the north pole

• intersects other magnetic field lines

• represents the strength of the magnetic field

Magnetic domains are:

• aligned in non-magnetic materials

• areas around a magnet

• found in all metals

• not aligned in permanent magnets

• groups of magnetic atoms aligned with each other

The direction of a magnetic field is:

• toward the magnet only

• away from the south pole and toward the north pole

• the same everywhere around the magnet

• away from the north pole and toward the south pole

• away from the magnet only
