Thank you all for the replies. Pauluk, yes, I can see that any impedance differences would send more current one way and therefore cause some net current and its magnetic field.
Ryan, I agree.
B-H yes, if the paralleled conductors were run in the same cable there would be less net current. However, as Pauluk mentions, if impedance of connections vary, even then net current would be set up.
(Oops, forgot the name of the other fellow), but I would first like to know what "leakage currents" are. ?? Most computer monitors start to jitter at anywhere from 0.5 uT to 1.2 uT. This would be caused by a net current in a circuit of 0.25A to 0.6A just one meter from the computer.
