about earth gravity,

[khaled]

what is the relation between the magnet we know [ N | W ]

 

and the inner core of the earth,

 

is it some kind of a special massive magnet,

 

or it works with different mechanism ..?

Did you mean [N | S] ?

 

And what does this have to do with gravity, which is the title of your post?

There is no magnet. Magnets would be metals charged with electrons, but, lo! Here unto is is delivered no charges. Yes yes!

Yes there is. This should explain how it works:

Also, magnets are not necessarily charged. Static charges do not create a magnetic field. Moving charges do.

aka permanent magnets

[Double K]

Would you liken earth as a "reactor" more like an electro magnet, or plasma reactor?

Not necessarily; this is true of electromagnets as well. Magnetic fields do not require any net charge, only relative motion of charges. i.e. the presence of static charge does not, by itself, imply the presence of a magnetic field.
