DC electromagnet strength: voltage or current?
Big but. If you increase the voltage/current, you will increase the power dissipated by the magnet. And if you double the voltage you will increase power by a factor of 4. Since the magnet has lots of turns stacked on each other the interior of the magnet can get hotter than the outside, and you can wind up cooking the insulation.
