Sorry, I should have explained the picture a little better. The equation corresponds with the arbitrary x and y axes seen in the picture. The colored lines are electron trajectories corresponding to different energies entering a magnetic field at, I believe, a 30 degree angle. The horizontal...

That's a good point, but I'm not sure how to make that with our design, it requires a gradient with a 2*(x^2 + y2) dependence if the image is like this: y | | | | bent by gradient field in this x-y plane | |_______________ x /\ \ \ ^electron enters through collimator

Well, how would we create it with electromagnets? We understand how they're made, but only in the context of one. Would you have to make multiple solenoids with varying current in some geometric configuration?

I'm working at a university to build a low-energy electron detector and it requires that we construct a magnetic field gradient. We know, through computer models, what the gradient should be, but we don't know how to make it. We would rather use rare-earth magnets as opposed to an...
