What is the magnetic field strength of?

Question

the human brain? (give me the range of fluctuation in gauss if you can please).

I know the magnetic frequency of the Earth is 1 gauss, how does this compare?

Answer 1

The standing magnetic field 1cm from the scalp has been estimated to be about 10pT (about 1e-7 gauss) and fluctuates by about 3fT (.03%).  In reality, the strength of Earth's magnetic field ranges from .3 gauss to .6 gauss, but this reduction makes little difference if you are comparing the Earth to your brain.

Answer 2

31 µT (3.1×10−^5 T) - strength of Earth's magnetic field at 0° latitude (on the equator)

58 µT (5.8×10−^5 T) - strength of Earth's magnetic field at 50° latitude

0.1 - 1.0 x10-^12 T - human brain magnetic field

NB.1 Tesla = 10,000 Gauss
