New research shows that light’s magnetic field is far more influential than scientists once believed. The team found that this magnetic component significantly affects how light rotates as it passes ...

Light has always been described as an elegant partnership of electric and magnetic fields, yet for nearly two centuries physicists treated the magnetic side as a quiet background player. New ...

In 1845, Michael Faraday discovered what’s known today as the Faraday Effect—which describes how light and electromagnetism are related. A new study revealed that the magnetic component of light ...

Optical or magnetic linear encoders handle high-res needs in dirty jobs. Linear encoders help minimize errors in motion transmission such as backlash, hysteresis, abbe errors, ball-screw thermal ...
