Norman F. Ramsey may not be a household name, but he was a giant of 20th-century experimental physics.

(PhysOrg.com) -- Used in Hollywood and the advertising industry to create exotic special effects, ferrofluids are seemingly magical materials that are both liquid and magnetic at once. In a study published today in Physical Review B, Yale electrical engineering professor Hur Koser and colleagues from the University of Georgia and Massachusetts Institute of Technology demonstrate for the first time an approach that allows ferrofluids to be pumped by magnetic fields alone. The invention could lead to new applications for this mysterious material.

Intense magnetic fields were probably generated in the universe shortly after the Big Bang, according to an international team led by Christoph Federrath and Gilles Chabrier of the CRAL (Centre de Recherche Astrophysique de Lyon, France). The project offers the first explanation for the presence of intergalactic and interstellar magnetized gas

While insulating against electrical currents

Nuclear magnetic resonance (NMR) is a powerful tool for chemical analysis and, in the form of magnetic resonance imaging (MRI), an indispensable technique for medical diagnosis. But its uses have been limited by the need for strong magnetic fields and big, expensive, superconducting magnets. Now Berkeley Lab scientists and their colleagues have demonstrated that they can do NMR in a zero magnetic field without using any magnets at all.

(PhysOrg.com) -- Completing the story they started by creating synthetic magnetic fields, scientists from the Joint Quantum Institute (JQI), a collaboration of the National Institute of Standards and Technology and the University of Maryland, have now made atoms act as if they were charged particles accelerated by electric fields.
