Effects of a very large magnetic field on the human body
Ever since reading about the NHMFL I have always wondered about this and asked several people without getting a good satisfactory answer. My question is, considering the simplest case let's say a uniform magnetic field with a very high magnitude constant both in time and space permeating a large room, what would happen to my body in such a field like if I was to just walk through it? How large would the magnitude need to be before I "feel" anything? One tesla is fairly large, would I feel anything? I imagine as we crank up the magnitude, I would feel queasy and sick. What if I crank it up to fifty teslas or a hundred teslas? Would it hurt? Would it mess up my synaptic potentials? Would I go crazy with a dysfunctional brain? Would I pass out or go into a coma? At what point will the damage become irreversible? What magnitude will cause death? With a high enough magnitude would molecules in my body start falling apart? What happens at hundreds of teslas? Thousands of teslas or millions of teslas?
The closest thing here I found was here in the accepted answer "a magnetar that would be 1000 miles away would kill us due to diamagnetism of water in our cells". 258
This is the kind of stuff I am looking for, the magnitude of the B-field and then its effect on a human body. Like "at 100T, your body would __ because __ and at 1000T, your body would _ because _" and so on.
If we allow changes in the magnetic field in time, does the induced electric field "hasten" the effects somehow? Would a strong enough E-field cause a shock within us burning our organs and killing us even if the average B-field is small but the db/dt is "large" for example?
I don't know if any experiments on biological samples have been done because artificially creating magnetic fields beyond a 100T or so hasn't been quite done yet much less sustaining them and observing the effects on a biological tissue. But if there are any cool references even if they are on theoretical grounds, that would be interesting.
Thanks.
Edit: Just to make the question more answerable, I'll focus only on static fields. Anyone know of any references/experiments regarding the effects of large magnetic fields on biological tissues? 75
