I actually have a question related to this. In my case, the magnetic field is coming out of the page and there is a positively charged particle initially at rest a distance "r" from the axis of the solenoid. Then, the current in the solenoid is flipped the other way instantaneously (all of the...

Ok, that totally makes sense now. By using infinitesimally small areas, the change in magnetic field as r increases becomes negligible. You are a life-saver :)

So I've been working on this for a while now, but I'm a little stuck. I think I see how to solve the problem below, just need a couple tips to get me over the hurdle. Homework Statement There are two infinite wires in the same plane as a rectangular loop. Geometries are displayed in the...

So I guess my ultimate question is how do I determine the limits and set up the integral using polar coordinates?

Homework Statement The conductor is cylindrically shaped with a radius of R. The hole on the inside is also cylindrically shaped with a radius of R/2. If a cross-section of this conductor is placed on an x-y coordinate plane, the hole would be centered on the x-axis at a distance of R/2 from...
