Some animals can sense the earth's magnetic field(磁场), while humans can't. This magnetic field guides a certain kind of fish when they swim a long way to a place and then back. How can this kind of fish do that? It is still a mystery. Scientists have no good answers yet.However...

There are some earth phenomena you can count on, but the magnetic field, some say, is not one of them. It fluctuates in strength, drifts from its axis, and every few 100,000 years undergoes a dramatic polarity reversal—a period when north pole becomes south pole and south pole becomes ...
(a) The earth is surrounded by a magnetic field generated by the magnetism in the core of the earth. Small magnetic grains in rocks will orient themselves to be parallel to the direction of the magnetic field pointing towards the north pole. (b) The geomagnetic polarity time scale shows ...
