Electromagnet, current vs voltage, same?

[supak111]

Would these two electromagnets be the same strength? I can NOT change turns, I can only change wire gauge and voltage.
What are the advantages if any of either one?

Electromagnet with at: 10vDC at 10amp - VS - 100vDC at 1amp

The strength of the magnet is proportional to (amps * turns).

Oh ok that answers my question then. 10v at 10amp would be 10x times stronger then. Thanks
