Directing magnetic field lines by using diamagnetic material

AI Thread Summary
Improving magnetic field strength at the surface of a magnet configuration using diamagnetic materials is a proposed method to guide magnetic field lines. The initial setup involves four anti-parallel magnets, while the modified design incorporates diamagnetic materials like Pyrolytic Graphite or Bismuth to redirect the magnetic fields. The goal is to increase magnetic flux density (B) for energy harvesting by encouraging a longer path for the field lines. The feasibility of this approach is questioned, with references made to established concepts like the Halbach array. Overall, the discussion centers on the potential effectiveness of using diamagnetic materials to enhance magnetic field strength.

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.
