I want to be able to estimate the force on various steel nails inside
MRI or other scanners with strong magnetic fields. You can assume the
nail is located where-ever the field is strongets.  Ideally I'd like
an equation where I can just input the strength of the field (I think
3T is common) and get the force out. I also understand there would be
a tourqe, that would be helpful as well.

There is no answer at this time.

Please note that many of the nails/bolts inside MRI scanners are
non-magnetic stainless steel.  So, in a prcatical sense, the force on
these items would be nearly zero.
