This project describes the construction of a 27 cm diameter, 50 cm long homogeneous Halbach array magnet. It consists of 23 rings, each with two layers of 12x12x12 permanent magnets. Design files are provided for those wanting to laser cut, CNC mill, or water-jet cut the positions of the magnets.…
The scanner design is a low-cost resource for demonstrating concepts like magnetic resonance, spatial encoding, and the Fourier transform in an educational setting. A significant part of the system design is open-source.
