FAQ
Frequently Asked Questions
Hannes Alfvén, a Swedish physicist, predicted them theoretically in 1942.
In plasmas with magnetic fields, such as the solar corona, planetary magnetospheres, and laboratory fusion devices.
Their speed depends on the magnetic field strength and plasma density; in the solar corona they can reach thousands of km/s.
They transport energy and momentum in astrophysical plasmas and are key to understanding solar heating and space weather.
