Depends how much magnetization is in your budget, or if the limit is determined by temperature (power density) or straight power. With "no" airgap, there may be advantage in increasing core area to move away from saturation, but the larger core means more wire length for the same amp-turns. There will always be some compromise that depends on allowed dissipation. | |

So if I understood you correctly, in a system with an airgap it doesn't matter, because it would be really hard to saturate the iron core in such case anyway. Conversely, if there is no airgap (which is the case in my system), material properties matter and I should be cautious about approaching the saturation point. Thank you for the advice about the permanent magnet, I'll consider that. | |
