0.9T Halbach Magnet for NMR

thingiverse

Square Halbach magnet designed specifically for the BY088-N52 magnets from K&J Magnetics (http://www.kjmagnetics.com/). To be used for testing NMR without requiring a superconducting magnet. Hall probe measurements agreed well with simulation. Print Settings Printer Brand: RepRap Printer: Prusa i3 Rafts: Doesn't Matter Supports: Yes Resolution: 0.2 Infill: 100 Notes: Printed using PETG, as it's both readily available and holds up better in liquid nitrogen environments than PLA or ABS. Post-Printing Assembly Be extremely careful if you try to assemble these magnets. They are very strong, and you'll be putting them into a position they don't want to be in. Expect them to fly out when you join two pieces together. Install the center plate before putting two pieces together, and don't remove until all three pieces are in place (but not fully tightened). Arrows have been incorporated into the print, indicating which way north should be aligned. When assembling the stack, make sure all layers are aligned identically with the layer below. Exercise extreme caution, and wear safety glasses.
