Creating an island paradise in a fusion reactor

In their ongoing quest to develop a range of methods for managing plasma so it can be used to generate electricity in a process known as fusion, researchers at the U.S. Department of Energy's (DOE) Princeton Plasma Physics ...

Magnetism boosts hydrogen production in model catalysts

Researchers at the University of Twente have shown how to improve the efficiency of hydrogen production in an experimental setup. They showed that the magnetic order of the molecules plays a critical role.

Magnetic field

Magnetic fields surround magnetic materials and electric currents and are detected by the force they exert on other magnetic materials and moving electric charges. The magnetic field, at a given point, is specified by both a direction and a magnitude (or strength); as such it is a vector field.

In special relativity, the electric field and magnetic field are two interrelated aspects of a single object, called the electromagnetic field. A pure electric field in one reference frame is observed as a combination of both an electric field and a magnetic field in a moving reference frame.
