Assumptions about magnetic feld
Assume AC current runs through straight wire. Current creates magnetic field. Lines of field are concentric to the wire.
Second wire placed parallel to the first wire, at a distance small compare to wavelength. Through this second wire current runs in opposite direction. Amplitude of second current is twice the amplitude of first current.
Will there be an area where magnetic fields from the two wires cancel each other?
