Project #44 Magnetic Fields
Educational Corner:
A magnet has a magnetic field, and a
battery has an electric field. The north and
south poles of a magnet are comparable to
the positive and negative terminals of a
battery.
Electric and magnetic fields affect each
other. If you place a magnet next to a radio
your reception can be disturbed.

1. There is an area around a magnet
where it can affect other objects,
called a magnetic field. It is
strongest at the ends of the magnet.
2. Slowly move your compass around
the magnet and watch its pointer to
see the magnetic field.
3. Shake the iron filings pack to
spread the filings evenly. Move the
magnet over the filings and you can
see the magnetic field in them.
4. Loop two paper clips together.
Hold them near the magnet and
move them around it to see the
magnetic field.
