On Wikipedia you can find info on magnetohydrodynamics

https://en.wikipedia.org/wiki/Magnetohydrodynamics
I'm think this refers to understanding the plasma fluid properties of the Sun where you have really strong magnetic fields, plasmas, acoustical waves and collisions.

Even Wiki gave physical explanation; I need to a siiimple meaning to get the what does it mean Magnetohydrodynamics!
 
Why don't you propose one here?

You know it involves plasma, you know a plasma is ionized which means it has an electric charge, you that like charges repel and that moving charges create a magnetic field which in turn will affect other nearby charges.

What do you mean by here?
 
Here means you say 'I think the definition of magnetohydrodynamics is _________________________. '
(fill in the blank with words.)
 
Hope this! why not!
