Re: Fun with perpetuum mobile
Variations of 100 or 200 nanoteslas almost every day. Up to 1000 is possible. Some of the variation is caused by magnetic storms on the sun, some of it from the rotation of the planet (the magnetic field is pushed away from the sun).
The field itself has a strength of 55000 nanoteslas where I live (goes down to 30000 near the equator.) I can't help thinking it'd be easier to find circumstances where you could take advantage of the fixed field than to harness the random fluctuations... but then, I am not a physicist.
