The tube axis is vertical, but I would like to see the ferrofluid hovering, attached to nothing. I will keep the coil idea in mind though, thanks.

I don't have a sketch, right now this is an abstract idea. The acrylic chamber would be cylindrical, with the electromagnets on either end. the fluid would not touch the acrylic chamber, and doesn't need to be a specific volume. I assume the shape of it would be determined by the magnetic...

Is there a way to fix that? Perhaps run it at a different frequency?

Well, magnetic fields move at the speed of light, which is 299 792 458 m/s. A 1 GHz DC signal would oscillate at 1,000,000,000 Hz. That means that the electromagnets would be turned on/off 1,000,000,000 times a second. If i invert the signal for 1 electromagnet, that means when one is off, the...

I don't have any articles for this info, just asking if it would be possible. To clarify, my idea is to use a DC power supply to switch each electromagnet on/off 1,000,000,000 times a second, or 1 GHz. Don't know if would work though. Also, why would it interfere with radio communication?

I am wondering if it is possible to use two electromagnets oscillating at about 1 ghz to suspend an amount of ferrofluid in an acrylic chamber. As I understand it, 1 ghz should be sufficient enough to get the ferrofluid away from each magnet, as after a quick google search, magnetic fields move...
