The magnetic field would vary with
the distribution of the cellular constitution.
Everything in-there is 'atoms' and 'ions'.
The cellular membrane would modify
any applied field because it, too, is
comprised of 'atoms'.
So, depending on the field strength,
you don't get a a uniform action, but
one that [literally] reflects the cellular
This is what "magnetic Resonance
Imaging" [MRI] is [why it gives detailed
