The speed of magnetic recording – a crucial factor in a computer’s power and multimedia capabilities – depends on how fast one can switch a magnet’s poles. An experiment at the Stanford Synchrotron Radiation Laboratory (SSRL) found that the ultimate speed of magnetic switching is at least 1,000 times slower than previously expected.

The time it takes for Earth's magnetic field to reverse polarity is approximately 7000 years, but the time it takes for the reversal to occur is shorter at low latitudes than at high latitudes, a geologist funded by the National Science Foundation (NSF) has concluded.
