Magnetic field strength On wire?

If 1 amp average DC current , as 7A peak DC pulsed current passes through a sealed module iron core inductor for X value mag field from 1.75mh, .6ohm, and then through a 2nd same inductor in series in same module, what is final magnetic field on the output wire? X or 2X field? A replacement as one inductor is needed to be configured. Wire coil electromagnet can also be made with way less turns and higher current injected for same field generated.
