In the two coils opposing magnetic fields, the zero magnetic field is read at the midway point between the two coils. Would that be the same if one of the coils was replaced by a coil with the same number of turns and radius but constructed with conductive wires having twice the conductance value of the previous one? Explain your reasoning.
