Mighty is very attached to electricity magnetism (as Faraday discovered). And the magnetism, magnetic fields, fields generally can move mountains.
For example, our sun (and other stars), the famous spots are areas where the magnetic field generated by the convection hydrogen / helium and heavy metals generated in our star push photons want to leave the outside and this material (hydrogen, helium and other metals or heavy materials) outwardly. Thus, the black areas are cold areas magnetic field generated by the convection of the star itself. They are so cold that it is “black”.
The Sun’s magnetic field, like any star, inside it is so complicated that even existing mathematical models are approaching to try to be as reality.
And it is that “we must be very man” to have a differential equations and solve them without approximations to a changing environment.
