2. Electromagnetic Source Mechanisms The electromagnetic source mechanisms involve the acceleration and scattering of low-energy particles already within the magnetosphere. In order for an irreversible ac­ celeration of trapped particles to occur, it is necessary that one or more of the three adiabatic invariants of the motion be violated.

As temperature of an object increases, the more total radiation is emitted by an object (Stefan-Boltzmann Law). Sun at ≈ 6000 °K emits radiation, electromagnetic spectrum

Intrinsic hydromagnetic fluctuations evi-dently occur in the surface layers of most of these stars. A beginning can be made on the interpretation of these results by anal-ogy with the solar magnetic cycle and the hydromagnetic processes observed in some detail on the sun.
