I have been trying to solve this problem without any success. Not homework, just curious how to solve this, I'm trying to deduce physical models. Honestly I have no idea how to attack it, so I'd really appreciate if you could please provide some help. This is electrodynamics applied to medical physics. Suppose n-dipoles are colocated in the ventricular tissue of the heart with a certain fixed horizontal depth, which we denote by x. Assume all these n-dipoles have constant dipolar moment, i.e they are continuously distributed. Now imagine a system of coordinates and suppose the n-dipoles are located at the points (x,y) where x is the fixed horizontal depth and y is the height (vertical distance between the dipoles), y is varying. How would you write the expression that describes the potential field generated by these n- dipoles? under the assumptions previously mentioned. I know it's an integral, but don't know how to attack this problem. Thanks in advance.
