FIGURE 4. MAGNETIC FIELD.
If the tabletop is gently tapped, the filings will move about and arrange themselves in a definite
pattern of lines about the magnet. The pattern shape is determined by the forces of the magnetic
field around the magnet. Notice that the lines are clear near the magnet and get less distinct
farther away. This is because the magnetic field is strongest near the magnet and gets weaker with
