The Danish physicist Hans Christian Oersted was discussing in the year 1820 about the possibility of electricity and magnetism being associated to one another, and in the process presenting it finally ...

A magnet produces a vector field, the magnetic field, at all points in the space around it. It can be defined by measuring the force the field exerts on a moving charged particle, such as an electron.

A Superconducting Quantum Interference Device (SQUID) is an extremely sensitive magnetometer that measures very subtle magnetic fields. It exploits the quantum mechanical properties of ...

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.
