Interplanetary Magnetic Fields
Science, 1962Preliminary analysis of Mariner II magnetometer data indicates a persistent interplanetary field varying between a least 2 and 10 gamma (1γ = 10 -5 gauss). The interplanetary field appears to lie mainly in the ecliptic plane, although there is a substantial, fluctuating, transverse component.

Physica B: Condensed Matter, 1995
Abstract After a summary of the observations of cosmic magnetic fields, I briefly discuss the status of dynamos, the use of electric circuits, the physics of magnetic explosions, the role of magnetic tension and our strongest magnet known, the radio pulsar. Finally I mention a few problem areas which may show a breakthrough in the near future.

Enhanced valley splitting in monolayer WSe2 due to magnetic exchange field.
Nature Nanotechnology, 2016Exploiting the valley degree of freedom to store and manipulate information provides a novel paradigm for future electronics. A monolayer transition-metal dichalcogenide (TMDC) with a broken inversion symmetry possesses two degenerate yet inequivalent ...

The study of magnetism and magnetic fields readily follows the study of electricity and is normally a second-semester topic in a first-year physics course. One of the difficulties that a teacher may encounter is that students often confuse magnetic poles with electric charges.

Observation of Dirac monopoles in a synthetic magnetic field
Nature, 2014Magnetic monopoles—particles that behave as isolated north or south magnetic poles—have been the subject of speculation since the first detailed observations of magnetism several hundred years ago.
