Magnetic Field Intensity?



I have a person with a question about magnetics. He has two magnetics
made by different suppliers, with the same basic design. Both magnetics
have the same magnetic force at 12vdc. But when they are tested at a
lower
voltage the results are not the same. This does not make sense to me
because
H = 0.628 NI / r

If the resistance is the same for both magnetics then why are they
getting
a lower magnetic field intensity?? Does the material that the coils are

wraped around make a difference?? Does the material the the coils are
packed in make a difference in the magnetic field intensity??

Thank you in advanced
