Electromagnet Comparison: Does Wire Size Impact Lifting Power?

[wmingin]

Good Morning!

Is it true, that supplied with the same voltage and current, an electromagnet with
10,000 turns of #40 wire will have the same lifting power as an electromagnet having
100 turns of #20 wire? (cores are identical).

Thank You All!

No, lifting power depends only on the current, and it is not simply proportional to the current.
For a given voltage, the current is proportional to VR^2/L for a wire of radius R and length L.

Thanks Very Much!
