One of the main tools scientists use to sort out chronology is the measurement of magnetic orientation in rocks.

But their ability to exit the other side, turning the circuit "on," depends on the magnetic orientation of the second strip.

As the tape moves away, the magnetic particles carry an imprint of the signal in their magnetic orientation.

The only catch being that they must be heated to apply the changes in magnetic orientation.

While the tracks they lay are parallel, the magnetic orientation of the data within the tracks is slightly different.

Most of the flows froze with a single magnetic orientation.

Note that north here is true north, so magnetic orientation must be corrected for magnetic declination.

One method, known as thermal-magneto-optic, stores a piece of information by shining a laser beam to heat a tiny spot and change its magnetic orientation.

Many animals use magnetic orientation based on the Earth's magnetic field to find their way home.

Also used to compare the orientation of a line to a magnetic or geographic orientation on a compass rose.
