STEM BOX: Levitation with Space Age Materials (Ages 12&Up with Adult Supervision) brain-teaser Radiocontrast agent

Radiocontrast agent

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

At the heart of every GlowRing is a Swiss Trigalight™ capable of powering its light output for many years

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

STEM BOX: Levitation with Space Age Materials (Ages 12&Up with Adult Supervision) brain-teaser Radiocontrast agentMagnetic 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
