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 ...

A new image shows the huge extent of a spiral galaxy's magnetic field. The galaxy NGC 4217 is a star-forming, spiral galaxy, similar to our own Milky Way, 67 million light-years from Earth in the ...

Assuming that the magnetic field guides only the emitting electrons while the radiation is weakly scattered cannot explain the directivity pattern in multi-spacecraft observations without invoking ...

A small voltage is like a near-flat plain with almost no water flow. ... A changing magnetic field within a coil of 50 turns will generate ten times the voltage of a coil of just five turns.

The polarized light image shows the black hole's magnetic field structure as a striking spiral. "What we're seeing now is that there are strong, twisted, ...
