Is it possible to produce a gradient magnetic field using three
orthogonal current coils ?
with the highest gradient point at the center of the coils ?

Hope you answer..

Yes, add their vectors.

The opposite directions cancel inside the loops. The field is
steepest in each wire. With three loops, it's at the octant.

OK, thanks.
yes, I think the strongest field is in the octant, but for the
gradient of the field,
I am not sure if the center is the strongest point,
somebody told me the center part may show a relatively homogeneous
region, gradient is not so high.
Is that so ?

should be 0 for both
