This persnickety number determines the strength of magnetic fields. It figures in everything from motors and generators to audio speakers. Oh, and without it we’d live in eternal darkness.

The film demonstrates an experiment using an apparatus to observe the behavior of electrons in a uniform magnetic field. It explains how electrons are accelerated by an electron gun and then deflected ...

Scientists have figured out a way to create and cancel magnetic fields from afar. The method involves running electric current through a special arrangement of wires to create a magnetic field that ...

Physicists from the Institute for Solid State Physics at the University of Tokyo have generated the strongest controllable magnetic field ever produced. The field was sustained for longer than any ...

Electric and magnetic fields are both components of an electromagnetic field. These two components occupy different planes relative to the cause of the electromagnetic field, for example a moving ...

A powerful new technique harnesses swirling plasma inside laser-blasted microtubes to produce record-breaking magnetic fields—rivaling those near neutron stars—all within a compact laboratory setup.

Scientists have figured out a way to create and cancel magnetic fields from afar. The method involves running electric current through a special arrangement of wires to create a magnetic field that ...
