Well, this is also a formula I was looking for at the time. My initial goal was to determine the devices dimensions and characteristics (including coils / electromagnets) stringer than the "usual" devices we see online. Unfortunately I was in a hurry (I had to build two devices to levitate a...
I wanted to point you to a thesis which was a great help to me, going into great details (and force calculus) about designing and building a repulsive levitator. Unfortunately it looks like the thesis is not online anymore. Yet the guy made a video of his final device :
You could reach out...
Hi Martin,
I went quickly through the video, and my guess is that he is building an "analog" levitator -- by opposition to a digital approach using an arduino, as I did. I won't be able to help regarding the analog approach, my electronics standard not being high enough. But if you are...
Hi onkkil,
Glad I could help. Although, I am nowhere near your knowledge of electromagnetics and physics (my usual field of work is software), so I won't be able to comment on your project. If I understand correctly, you will build some sort of "invert pendulum" onto the levitated magnet, which...
Thanks for sharing.
So according to this list I think we're dealing with case 10: "Repulsion between and electromagnet and a magnet, with sensors and active control of the current to the electromagnet used to maintain some distance between them."
I'm pretty sure I came across this youtube...
Hi all,
I am a software developer who is getting more and more interested in electronics (having raspberry pis and arduinos, I love to build fun stuff with these) and currently having fun with magnets.
Happy to join this forum and eager to learn plenty!
Hi navivanuva,
How coincidental, I just subscribed to this forum to get answers, while I try to build this kind of device !
My goal would be to levitate a 2kg object using two of these devices. As you just started a topic here, do you mind if we share the topic to compile our findings ? If you...
