Magnetic trap for cylindrical diamagnetic materials

A method of arranging a diamagnetic rod comprising:

• levitating a diamagnetic rod above a contact line at which a first magnet contacts a second magnet, the first magnet and the second magnet having diametric magnetization in a direction perpendicular to the contact line, and the first magnet and the second magnet making up one magnetic trap among an array of magnetic traps mounted on a template substrate;
• depositing a plurality of diamagnetic rods onto the array of magnetic traps;
• capturing, by the array of magnetic traps, a number of captured diamagnetic rods, among the plurality of diamagnetic rods, corresponding to a number of magnetic traps in the array of magnetic traps;
• cleaning the template substrate to remove from the template substrate any un-captured diamagnetic rods among the plurality of diamagnetic rods;
• and
• bringing the captured diamagnetic rods into contact with a target substrate to form wiring on the target substrate.
