WEST LAFAYETTE, Ind. - Researchers at Purdue and Duke universities have developed a technique that uses a magnetic field to selectively separate tiny magnetic particles, representing a highly ...

A Hall-effect sensor is a transducer that converts a magnetic field directly into a usable electrical voltage. It enables ...

If you made a motor out of a magnet, a wire coil, and some needles, you probably remember that motors and generators depend on a rotating magnetic field. Once you know how it works, the concept is ...

As Cassini continues its orbital finale around Saturn it has picked up on some interesting observations of Saturn’s magnetic field. Data gathered from Cassini’s magnetometer instrument have shown that ...

The evolution of active regions generally has prevented the unambiguous detection of differential rotation by tracer or spectroscopic methods in disk-integrated solar and stellar observations. However ...

New simulations suggest magnetic fields hold the key to forming black holes that defy known mass limits. When powerful ...

In 2023, astronomers observed a black hole collision that defied established theories. Two enormous black holes spun into ...
