Directing magnetic field lines by using diamagnetic material

In summary, the conversation discusses the possibility of using diamagnetic materials to improve the magnetic field strength at the surface of a magnet configuration. The idea is to redirect the magnetic field lines to take a longer path outside the magnets, rather than the shorter path. This idea is being considered for energy harvesting purposes and is being compared to the use of a Halbach array. The person asking the question also clarifies that they are referring to the magnetic flux density B, and not H.

TL;DR Summary
Is it possible to increase the magnetic field strength of magnets by directing the magnetic field lines with diamagnetic materials?
I want to improve the magnetic field strength at the surface of a magnet configuration by utilizing diamagnetic materials to guide the magnetic field lines. I have not the proper equipment to measure the effect myself but would this work?

This is the initial configuration with four magnets side by side anti-parallel

This would be the second configuration where the four magnets are separated by a diamagnetic material (orange) such as Pyrolytic Graphite or Bismuth.

The Idea would be to redirect the magnetic fields to take the longer path outside the magnets instead of going the short path.

Is this idea feasible?

Hi

Yes, I know the Halbach array and I will test this as well. But just out of curiosity I would like to know if Diamagnetic materials would work too.

I want to increase the magnetic flux density B at the top of the magnet. I would like to use this for energy harvesting so I get a big B-field and a fast change of the magnetic flux in a coil.
