Less than 50 Qty. 10 in the immediate term I see about the bobbins. 0 experience :) Presently I'm wondering if I can just use a pair of inductors or a couple of the coils that are for sale as levitation kits.

Little more looking at it appears this would be the U-shape wrapping I have 34AWG wire represented here 300 turns on each leg.

Yes those are all good questions. I've not done this before. Is this u shape core and application of it what @Baluncore was suggesting? You mention a bobbin as if that would be inserted in the center of the U shape. I don't think that would result in the flux path I'll need. I was thinking the...

OK If I use a U shaped core I have two options. A narrow one that ill fit inside a cavity or a wider one that ill fit outside the cavity. I'm thinking the outside one will be the best option given the strength of field I need to generate and the distance between the end of the EM and device...

I could use some help to point me in a direction. I am looking to create an electromagnet roughly 1/4" square x 1-3 inches long. The flux needs arc across the tip so it can reach a device that will be ~0.25" away. So I'm thinking of wrapping the wire end over end rather than around the rod. I'm...
