How would it be possible to fluctuate one magnet between two magnets?

Thanks

That question is very unclear. Can you rephrase it? What exactly is it you want to do?

Did you give it a try?

I want to have one set of magnets go up and down really fast between two other sets of magnets.

No

And what force are you going to use to make that happen?

...why? I mean, it's peculiarly specific. If you want a magnet to go up and down, that's easy enough (at least in principle) with an electromagnet driven by an alternating current. Some engineering may be required depending on how big the magnet is. Why do you demand magnets?

I thought it would be interesting.

Interesting or not, I don't see how it's possible to do with permanent magnets. If you use electromagnets, and probably some control electronics, then sure it's doable.

Holy smokes, rtf, is it hard to squeeze information out of you. If you want help, you need to tell us what you need help with! Don't leave us to guess. Live a little - try writing two sentences in a reply rather than just one.

Yeah. @rtf -- We try our best to be helpful here at the PF, but so far you have given us so little to go on, it's not been possible.

So this thread is closed for now. Please start a private conversation with me (click on my Avatar and Start a Conversation), and send me drawings of what you are asking about. Also let me know why you are asking these questions -- what would you like to do?

Once I understand what you want to ask, I can help you with a follow-up post in this thread here and re-open it. Thank you.
