The Geek's Raven
[An excerpt, with thanks to Marcus Bales]

Once upon a midnight dreary,
fingers cramped and vision bleary,
System manuals piled high and wasted paper on the floor,
Longing for the warmth of bedsheets,
Still I sat there, doing spreadsheets:
Having reached the bottom line,
I took a floppy from the drawer.
Typing with a steady hand, I then invoked the SAVE command
But got instead a reprimand: it read "Abort, Retry, Ignore".

What are some practical applications of natural magnetic fields, other than the directional compass?

All moving electrically charged matter creates natural magnetic fields. Hence, natural magnetic fields of all types, and intensities, are all around us. We know about the directional compass. What are some other practical applications of the many natural magnetic fields around us?
