Magnet arrangement for producing a field suitable for NMR in a concave region

A kit for performing measurements using NMR techniques comprising:

• a first plurality of magnets shaped to form rectangular prisms;
• a second plurality of magnets shaped to form rectangular prisms;
• a first backplane forming a pentagonal prism;
• and
• a second backplane forming a pentagonal prism;
• wherein the first backplane and the second backplane abut at one side to form an angle;
• wherein the first plurality of magnets are positioned in a row on a top surface of the first backplane to form a left half, and the second plurality of magnets are positioned in a row on a top surface of the second backplane to form a right half, such that left half is symmetric to the right half on one side, wherein the first plurality of magnets and the second plurality of magnets are positioned at an interior of the angle.
