The NMR permanent magnets are NdFeB magnets and come in multiple models, each with unique specifications and dimensions as illustrated in the chart below. Models 1 - 4 are enclosed in a 4 sided shell as depicted in the picture above. Model 5 is enclosed in a C-shaped shell.

A 10 mm sample is used for field uniformity calculation.
