Addition of iridium leads to increased electron localization and stronger spin-orbit coupling between 3d electrons of iron and cobalt and 5d electrons of iridium, significantly enhancing the magnetic ...

This video explores the nature of magnets and how they create invisible magnetic forces. It explains the origin of magnetism, how magnetic fields are formed, and the role of electrons in generating ...

Like Earth, Mars once had a strong magnetic field that shielded its thick atmosphere from the solar wind. But now only the magnetic imprint remains. What's long baffled scientists, though, is why this ...

Magnetic bead separation is a fast, effective, and clean process that scientists use as an alternative to filtration and centrifugation techniques for separation. Magnetic beads and particles can be ...

First ever supercomputer simulations of Mars with a fully molten core could explain the Red Planet's unusual magnetic field. Billions of years ago, Mars had an active magnetic field. Mysteriously, its ...
