An important step towards live imaging in proton therapy

Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) want to build the world's first prototype that tracks moving tumors with magnetic resonance imaging (MRI) in real time during proton therapy. They are combining ...

A neuromagnetic view through the skull

The brain processes information using both slow and fast currents. Until now, researchers had to use electrodes placed inside the brain in order to measure the latter. For the first time, researchers from Charité - Universitätsmedizin ...

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.
