I recently had a head/neck MRI for chronic pain on the left side of my
head, neck and back, ringing ears and dizziness.  The scan went down

From what i've read, it sounds like the permeability
of a conductive enclosure will increase the density
of the lines of magnetic flux within the conductor,
so that the magnetic field within the enclosure
