I have talked about the course I teach for elementary education majors before (videos for education majors, Spring Course reflections). Anyway, the nature of the course is that students collect ...

(PhysOrg.com) -- A new mechanism will make it possible to switch data storage in the future. Researchers at the Max Planck Institute of Microstructure Physics in Halle use a short electric pulse to ...

It is not known when humans first noticed the attraction or repulsion between pieces of magnetic material. The first important device depending on these forces was the magnetic compass, which is ...

The quantum Hall effect, a fundamental effect in quantum mechanics, not only generates an electric but also a magnetic current. It arises from the motion of electrons on an orbit around the nuclei of ...

Next generation electronic devices face major technical challenges, which will affect both power management performance and efficiency. Increasingly, conversion and power management applications are ...

A magnetic field will apply a force on a single moving charge, and it will also exert a force on a current on which is a collection of moving charges. The force encountered by a wire of length l ...

Magnet technology has advanced, year-over-year, pulled by the desire of scientists for ever-higher magnetic fields. But progress has been paced by new developments in properties of materials needed to ...
