Origin of magnetic fields may lie in special relativity's spacetime distortions

(PhysOrg.com) -- Magnetic fields play an important role on scales ranging from the sub-atomic to the cosmic, from particle spins to galaxy clusters. Although scientists know how to create and manipulate magnetic fields, as well as use them for a variety of applications from computers to credit cards, they still don't have a universal theory of how magnetic fields initially originated in astrophysical settings.

Academics / General Science : Physorg Features (yesterday)

(Phys.org) —The discovery of the Higgs boson at the Large Hadron Collider (LHC) in 2012 marked an important step toward understanding the origin of the mass of fundamental particles. Since mass plays a major role in gravity, the Hig... Read Post

Scientists find metallic magnet with largest yet atomic displacement during thermal expansion

Academics / General Science : Physorg Features (4 years ago)

(PhysOrg.com) -- Although most materials change shape in the presence of a magnetic field, the change is usually very small. In a new study, scientists have found that a certain magnet containing manganese experiences a change in th... Read Post
