the relationship between the static magnetic field and translational force in MRI ?

Question

Question

Answer 1

Answer #1

MRI requires a homogeneous magnetic field over the entire field of view and thus, there is little translational force within the bore of a magnet.

So the static magnetic field and the translational force are directly proportional to each other.
