Earth's magnetic field is characterized by a puzzling hemispheric asymmetry. Calculations of core dynamo processes suggest that lopsided growth of the planet's inner core may be part of the cause.
A close-in exoplanet is triggering stellar flares and self-destructing. This is the first direct evidence of planet-star ...
The universe is soaked in weak-but-persistent magnetic fields. Despite decades of research, astronomers still aren't exactly sure where these magnetic fields came from. But new research suggests they ...
Earth's magnetic field lines travel in continuous closed loops. (Image credit: VectorMine via Getty Images) And just to make things that little more confusing, what we call the North Magnetic Pole ...
Magnetic reconnection, in which magnetic field lines break and reconnect to change their topology, occurs throughout the universe. The essential feature of reconnection is that it energizes plasma ...

Magnetic viewing films are pretty neat things to play with anyway, and can even be used to read hidden messages. Continue reading “Magnet Clock Makes Field Lines Visible” → ...
It would be useful, then, to be able to control, limit or shape magnetic fields from a distance. Useful, but apparently impossible. For, in 1842, Samuel Earnshaw, a British physicist, demonstrated ...
Magnetic Field Lines: Magnetic field is an important topic in physics, which starts to elaborate at the secondary level. CBSE introduces this topic in Class 10 and then dives into details in ...
Our rating: False. Based on our research, we rate FALSE the claim that a compass wouldn't work if Earth is spherical. Compasses orient themselves to the Earth's magnetic field lines.
150,000-year history of Earth's magnetic field reveals clues about the climate when early humans were spreading out of Africa; Scientists discover strong, ... creating magnetic field lines.
