The famous hoverboards of Back to the Future haven’t quite gotten here yet, but that hasn’t stopped anyone with a unique personal vehicle from using the name any time they need some quick marketing.

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 ...

Renesas is claiming “total stray field immunity” for a automotive-grade magnet-free inductive rotation position sensor that works up to what the company describes as “600,000rpm (electrical)”. “We are ...
