I have a question regarding Magnetic Fields

In summary, the conversation discusses the possibility of generating a magnetic field similar to Earth's by using a superheated iron ball inside a heated and pressurized plasma globe, with an outer shell to keep it all together. The individual is curious about the shape, size, and generation of magnetic fields and is interested in learning more about the topic. They are also pointed to the concept of Dynamo Theory for further information.

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.

Looks cool, thanks for the info.
 

FAQ: I have a question regarding Magnetic Fields

How are magnetic fields created?

Magnetic fields are created by moving electric charges. This can occur naturally in the form of lightning or in the Earth's molten core, or it can be created artificially through the use of electricity.

What is the difference between a magnetic field and an electric field?

A magnetic field is created by moving electric charges, while an electric field is created by stationary electric charges. Additionally, magnetic fields only exist in the presence of a moving charge, while electric fields can exist in the absence of a moving charge.

How do magnetic fields affect objects?

Magnetic fields can exert a force on objects that have a magnetic property, such as iron or steel. This force can either attract or repel the object, depending on the orientation of the object's magnetic field.

Can magnetic fields be shielded?

Yes, magnetic fields can be shielded by materials that are highly permeable to magnetic fields, such as iron or steel. These materials redirect the magnetic field away from the area they are trying to protect.

How are magnetic fields used in everyday life?

Magnetic fields have many practical applications in everyday life. They are used in generators to produce electricity, in motors to create motion, and in MRI machines for medical imaging. They are also used in credit and debit cards to store information, and in speakers to produce sound.
