Magnetism

The physics of magnetic materials and phenomena.

Almanac A Spiral Instead of a Mile
  • How does bending a particle's path into a spiral let it reach higher speeds without a longer machine?
Almanac The Stars and the Hard Drive, Explained
  • What is the difference between an antiferromagnet and a ferrimagnet in Louis Néel's classification of magnetism?
  • How did Néel's ferrimagnetic materials become the basis for magnetic data recording?
Finding Sensitivity increase of 3D printed, self-sensing, carbon fibers structures with conductive filament matrix
  • How can a mechanical 'breaking-in' process irreversibly increase the strain-sensing gauge factor of a 3D printed continuous carbon fiber beam?
  • What role does thermal residual stress from the 3D printing process play in causing the local progressive fiber failure that boosts sensitivity?
  • In what ways can piezoresistive carbon fiber reinforcement let a 3D printed structural part also function as its own strain gauge?
