z plane refers to the z-y plane. w is the radius of the ring of charge. positive z direction current on top of ring and negative z direction current on bottom of ring (counterclockwise current flow)
This is a simple problem if you work with only magnitude and consider the symmetry of a ring. However, I am taking a detailed approach, and I am not getting the correct answer. Could you please look over my math?
a evenly distributed ring of charge on the positive Y-Z plane has a current, I...
