Some angles are repulsion, attraction and no effect. These are segments of positive current flow. You apply the "fingers, thumb, palm" flux/current/direction rule, to verify that I correctly identified those angles as attraction, repulsion or neutral.
Edit: I had a new idea this apparent right angle Lorentz force can be described as the sum of two attraction/repulsion vectors.
I am studying this lecture to see if I can master dipole charge mathematics and adapt it to describe Lorentz force: Lec 4 | MIT 8.02 Electricity and Magnetism, Spring 2002
The important part, to me, is summarised at 8:00.
This Yale professor is great, too:

(3. Gauss's Law I )
He describes dipole forces there, too. minute 9:00
