Magnetic Field
Posted by JAC on 1/25/2011, 5:53 am
Check the change of the magnetic field recorded at a magnetometer station in Alaska.

There are three component directions to the field:

1)  north-south: shown in black
2)  east-west::  show in red
3)  vertical, i.e. ground to sky:  shown in blue

Data is plotted for the last month.

Notice the big drop in the red component (east-west).

A 10% reduction in just 1 month.
