What is shown by the pattern of iron filings around these two magnets? A. Opposite poles repel because no magnetic field forms between them.
B. Like poles attract because the magnetic field lines extend between them.
C. Like poles repel because the magnetic lined bend away from each other.
D. Opposite poles attract because the magnetic field lines cross each other.
