Question: Two very long, parallel wires carry equal currents in opposite directions. (a) Is there any place that their magnetic fields completely cancel? If so, where?

Two very long, parallel wires carry equal currents in opposite directions.

(a) Is there any place that their magnetic fields completely cancel? If so, where? If not, why not?

(b) How would the answer to part (a) change if the currents were in the same direction?
