I'm having a ton of trouble with this question
Basically I have a spiral coil running around the z-axis with radius 'a' height '2b' and pitch 'c'. The point (x,y,z) = (a,0,0) is on the spiral and n = 2b/c (that's the number of turns on the spiral). There's a steady current running through the spiral towards the positive z direction. I'm being asked to find the line integral of B dot dl calculated along the circle of radius R>a (in the xy plane) in the counter clockwise direction if seen from the positive z direction.
the attachment is a fairly horribly drawn diagram of it..
I honestly don't even know where to start, but I think I'd be fine if someone could at least point me in the right direction of finding B... Lemme know if any extra info is needed..
