magnetosonic
Magnetosonic refers to phenomena involving the interaction of magnetic fields and sound waves. In plasma physics, magnetosonic waves are a type of wave that can propagate through a magnetized plasma. These waves are distinct from acoustic waves and Alfvén waves, possessing properties of both. The speed at which magnetosonic waves travel depends on the strength of the magnetic field and the plasma density and temperature. They can be excited by various processes, including solar flares and geomagnetic substorms.
In geophysics, magnetosonic waves can be observed in the Earth's magnetosphere. These waves play a role in
