By power, I assume you mean flux.

Yes. I'm looking to get maximum flux density. The electromagnet will
only be used in a 12 vdc momentary burst so I need maximum capability
in an instant for an instant.


Current and voltage are linked by this equation :

U = L di/dt + R i

You can't have one without the other.
