I have a question regarding Magnetic Fields

Click For Summary
SUMMARY

The discussion centers on the generation of magnetic fields, specifically exploring whether a superheated iron ball in motion within a heated, ultra-pressurized plasma globe could produce a magnetic field similar to that of Earth. The concept draws parallels to the dynamo theory, which explains how celestial bodies generate magnetic fields through the motion of conductive fluids. The inquiry emphasizes the importance of pressure and heat in maintaining the iron ball's position and the potential for magnetic field generation in a vacuum environment.

PREREQUISITES
  • Understanding of dynamo theory and its principles
  • Knowledge of magnetic field generation in conductive materials
  • Familiarity with plasma physics and its properties
  • Basic concepts of thermodynamics related to heat and pressure
NEXT STEPS
  • Research the principles of dynamo theory in detail
  • Explore the properties of plasma and its role in magnetic field generation
  • Investigate the effects of pressure and temperature on magnetic fields
  • Study real-world applications of magnetic fields in astrophysics
USEFUL FOR

Astronomy enthusiasts, physicists, and students interested in the generation and properties of magnetic fields, particularly in relation to celestial bodies and plasma dynamics.

If you were to take a superheated iron ball (say a heavily scaled down version of the Earth's core) and set it in motion inside of a heated and ultra-pressurized plasma globe with another light hard coating ontop of it also set in motion, would that generate a magnetic field similar in shape to Earth's if it was done in a vacuum? I'm trying to think of something similar to this that generates a magnetic field...I kind of have the vision of a ball being kept heated by the pressure and the heat of plasma (or magma in a literal sense) with another shell outside of it keeping it all together under pressure so that the ball stays equal in the center. This is not a homework question, its just for my own curiosity about magnetic fields (shape, size, generation).

I'm fairly new to astronomy so be gentle.
