[QUOTE="Mahonroy, post: 6830067, member: 731533"] [B]TL;DR Summary:[/B] Coil Around A Tube - Iron Cylinder Inside Tube - How To Determine How Many Wire Turns And Power Required To Hold About 500 Pounds On Iron Cylinder Hello, I am wanting to wrap a coil of wire around a tube, suspend an iron cylinder in the tube, energize the coil, and have it be able to suspend around 500 pounds on the iron cylinder. I was playing around with some online calculators for coils, and didn't really get anywhere, so I figured I would check with you guys. I am under the impression that when I energize the coil, that it will create a magnetic field that will apply a constant force in one direction on the iron cylinder. So while its energized, the iron cylinder should be constantly wanting to travel in one direction. I understand that if the magnetic field is too strong, the cylinder will want to continue to travel up even with the weight. And if its too week, it won't be able to suspend the weight and it will fall. This is fine for the exercise - I'm just trying to figure out a ballpark. I am under the impression that I could fine tune this by adjusting the voltage slightly. Am I understanding this correctly or do I have this wrong? Does anyone know how to calculate roughly what kind of coil I would need with some headroom? I'm thinking of using a 1" PVC pipe to wrap the coil around (1.315" OD, 1.029" ID), and then a 1" OD iron cylinder to fit in the PVC pipe. Thanks and any help or advice is greatly appreciated!
