That is hard to say.  Given the bilateral symmetry of the human body
and the roughly two-dimensional aspect of the cross section of the
human trunk (we are more flat, in the abdomen, than round), it might
be problematical to get the correct angle or "spin on the ball" (to
use a billiards term) in order to accurately control the "pill".  I
don't know if there are more sophisticated ways to control a metallic
object with dynamic magnetic fields.  I suspect that magnetic strength
is not the issue, but rather complete accuracy of control.
