what other knife do you know that will levitate above N52 magnets indefinitely

How Differential Gear works (BEST Tutorial)

Four neodymium “N52” super strong permanent magnets – measuring 1 cm3 (pull force 3 kg each)

As the electrons produced by the gaseous tritium are so low in energy

and that anything closer than ~0

STEM BOX: Levitation with Space Age Materials (Ages 12&Up with Adult Supervision) brain-teaser what other knife do youMagnetic Levitation Few materials can be made to magnetically levitate stably above the magnetic field from a permanent magnet. Although you can obviously and easily achieve magnetic repulsion between any two magnets, the shape of the field causes the upper magnet to push off sideways, rather than remaining supported, rendering stable levitation impossible for magnetic objects (see Earnshaw's Theorem). Strongly diamagnetic materials, however, can
