The idea of levitating off the ground has been a staple of science fiction dreams and human imagination since time immemorial. While we don't have our hoverboards just yet, we do have the very real ...

Eddy currents are specialized electric fields that are generated in the presence of a magnetic field and are often seen as a secondary field. An Eddy current can be produced by both electromagnets and ...

Eddy current displacement sensors (ECDS) represent a mature, yet continuously evolving, non-contact measurement technology that utilises the principles of electromagnetic induction. When an ...

Unlike mechanical brakes, which are based on friction and kinetic energy, eddy current brakes rely on electromagnetism to stop objects from moving. Eddy currents are created when a conductor passes ...

A magnet sliding down a copper ramp is slowed by magnetic fields from eddy currents induced in the tube. A magnet sliding down a Plexiglas ramp is unaffected. A magnet sliding down a brass ramp goes ...
