In case you have difficulty finding a strong enough field,
there is a company in St. Louis that makes a medical device
that creates 3D fields strong enough to rip a piece of
metal around inside the brain under computer control for
Parkinson surgery.  

Their fields are in excess of 1 to 3 tesla, I believe.
 Anyway the fields are generated using helium cooled
superconducting coils.  

Just in case you have difficulty getting the field strength
you need, you might be able to use their equipment.
