Over the surface of the earth may not add up to much.
"A refrigerator magnet is 100 gauss, a strong refrigerator magnet. The typical strength of the Earth's magnetic field at its surface is around a half a gauss. So those are everyday units of magnetic fields. There are 10,000 gauss in one tesla."
" about 20,000 times weaker than the Earth’s global magnetic field.”"
"A nanotesla is equivalent to one gamma, a unit originally defined as 10−5 gauss, which is the unit of magnetic field in the centimetre-gram-second system."
They may simply be viewing 'EMI' from my magnet collection?
I suspect they have identified my collection of buckyballs.
Can this magnetic field be affected by glacial melt or glacial freezing (Ice Ages)? Or vice versa?
On a personal problem. I have an apartment in which there is a 5 volt current at the faucet emptying into the bathtub. Some people can feel it. I cannot. When we turn the whole apartment’s electricity off, there is still 5 volts at the faucet. Is this dangerous, is it safe to rent my apartment out??? Would you rent it knowing that info? What else can I do? This is the first complaint about that in 30 years. The house was shaken by the Mineral, VA earthquake in 2011.
