(Phys.org)—Move over, Siri. Some researchers from the University of Rochester in collaboration with a University of California, Berkeley, mathematician/crowdsourcing entrepreneur, have come up with a killer personal assistant ...
A dipole magnetic field, created by a ring current, is the most fundamental type of magnetic field that is found both in laboratories and in space. Planetary magnetospheres, such as Jupiter's, effectively confine plasma.

Listening to electromagnetic waves around the Earth, converted to sound, is almost like listening to singing and chirping birds at dawn with a crackling campfire nearby. Such waves are therefore called chorus waves. They ...

Space is not empty, nor is it silent. While technically a vacuum, space nonetheless contains energetic charged particles, governed by magnetic and electric fields, and it behaves unlike anything we experience on Earth. In ...
