Hello fellow modelers, converters, kit bashers and the like i'm in need of some creative assistance. So I've been building an arterial webway portal for my dark eldar and the central Idea behind undergoing this project was to make the portal levitate in the center of a 5" base As you can see in the pictures posted this is what i have so far. The portal is made of a 1" rare earth magnet and the surrounding magnets are made of a series of 1/4" magnets in opposite polarization they are + - + - and so on and the magnets on the floor are also doing the same. In my head I thought the magnets would push and force the magnet to be in suspense because it had no where to go. Unfortunately... It worked out much better in my head than in real life. The ball just seems to attract to one of the magnets on the ground and proceeds to break whichever magnet it chooses to stick to. Any advice would be fantastic or a point in the right direction would but just as great.

I don't get the + - thing...

In your place, I would have done something like this:
Magnets on base all with same orientation, let's say minus towards the portal (not alternating), "d12” or "d20" portal with magnet on sides, let's say minus outwards.
A magnet sphere will turn so that its + or - pole matches the opposing static ones, where on a polyhedron, you choose and glue magnets simulating a monopole.

Maybe, and just maybe, just the four central magnets - same orientation - may do the trick also with the sphere...

Also, but I'm sure you were absolutely precise, an error of 1mm in magnet disposition disrupts the balance.

What you're trying to do is impossible. Stable magnetic levitation cannot be achieved with static magnetic fields, for various complicated physics reasons (Earnshaw's theorem). You can simulate levitation with a lot of fairly unobtrusive methods, which is the way I'd advise you to proceed.

The supply does not get to make the demands.
