24-570 vs 25-500
24 AWG copper wire is 0.0842 Ohm/m @ 20C
25 AWG is 0.106 which is approx 25% more resistant/m
Assume the 24 AWG coil has approx 14% more wire length (570 winds vs 500) then it will still be less total resistance (hence stronger coil)
Saying all that I like paddys answer above better, but I don't know who Victor is![]()
