SUMMARY
The discussion confirms that the lifting power of an electromagnet is determined by the current flowing through the wire, not merely by the number of turns or the wire gauge. Specifically, for a given voltage, the current is influenced by the formula VR^2/L, where R is the wire radius and L is the wire length. Therefore, an electromagnet with 10,000 turns of #40 wire will not necessarily have the same lifting power as one with 100 turns of #20 wire, as the wire's resistance and the resulting current play critical roles in performance.
