Magnetic sensors detect moving ferrous metal. The simplest magnetic sensor consists of a wire coiled around a permanent magnet. A ferrous object approaching the sensor changes magnetic flux through ...

Magnetic Resonance Imaging (MRI) is an indispensable tool in modern medicine; however, its sensitivity to patient movement can significantly impair image quality. Motion correction techniques have ...

Scientists have uncovered a new way to control magnets using flashes of light lasting less than a trillionth of a second. The approach triggers unusually large magnetic motion without direct contact ...

We see our share of pitches for perpetual motion machines in the Hackaday tips line, and we generally ignore them and move along. And while this magnetic levitation motor does not break the laws of ...

Beckhoff’s AL8000 linear motors can now deliver greater accuracy and synchronization with the company’s new TwinCAT Cogging Compensation software. According to Beckhoff, this software enables linear ...
