Okay so i need some help with some math.
You see i'm trying to figure out the Correlation between an objects Mass, it's Rotation and it's Magnetic Field it produces along with how much energy that Magnetic Field has.
Example: Let's say i can make a magnet field by spinning a ball of molten metal 1 meter in diameter at 1,000 RPM. Exactly how strong would that Electromagnetic Field be?
Also, if it's not possible to create magnetic fields by spinning molten metal then how does the earth produce it's magnetic field? (I genuinely might be wrong so i want a genuine answer on why.)

Magnetic fields are produced through the movement of electric charge. Molten metal has no net charge, and so rotating it will not produce a magnetic field.
Use some Google-fu to find the maths behind magnetic fields. I learnt everything you need to describe them in first year undergraduate physics; it shouldn't be hard to find.

Energy is not a property of magnetic fields
Potential and Force is a more useful term here
