Three things:

  1. The planets rotation.
  2. The energy lost as the planet cools
  3. Both of the above driving movement of the molten iron in the core of the planet.

A region in a ferromagnetic material has a large number of atoms which aligh magnetic fields is called?

A region in a ferromagnetic material with aligned magnetic fields is called a magnetic domain. These domains exhibit a collective magnetic behavior, where the majority of atomic magnetic moments align in the same direction, contributing to the overall magnetization of the material.


What is the region of a magnetic field?

The region around a magnet or current-carrying conductor within which the magnetic force is exerted is called the magnetic field. Magnetic fields are three-dimensional and extend infinitely in all directions from the magnetic source.


What is a region of space that has a physical quantity called?

A region of space that has a physical quantity associated with it is called a field. Fields can describe properties such as electric and magnetic fields in physics, or temperature and pressure fields in fluid dynamics. These fields assign a value to each point in space based on the physical quantity being studied.


What is the definition for Magnetic Domain?

A magnetic domain is a region within a material where the magnetic moments of atoms are aligned in the same direction. These domains can change size, shape, and orientation in response to external magnetic fields.


What is a small region in a piece of iron where atomic magnetic line up in the same direction?

A small region in a piece of iron where atomic magnetic moments align in the same direction is called a magnetic domain. These domains can be influenced by external magnetic fields and can change their orientation, affecting the overall magnetization of the material.


What is clustered region of aligned magnetic atoms called?

Technically impossible . In a rock , ferromagnetism can create poles , but not in atoms . Atoms cannot be magnetic . Molecules can be polar , which leads to Van der Waals links , but a region's molecule cannot become all lined in the same directions . http://www.youtube.com/watch?v=4VmMr9TWzY4 http://media-2.web.britannica.com/eb-media/65/265-004-9B256ADC.gif Pretty simple , as a matter of fact .


What is the region around a magnet in which magnetic forces act called?

A Magnetic Force


What is the magnetic force exerted in the region around a magnet called?

The magnetic force exerted in the region around a magnet is called a magnetic field. It is a vector field that describes the magnetic influence of the magnet on other objects or moving charges.


The region around magnet where the magnetic force is exerted is known as its?

That is called its magnetic field.


What is the area of magnetic force called?

The area of magnetic force is called a magnetic field. It is a region around a magnet or current-carrying wire where magnetic forces are experienced.


What is net magnetic field?

The net magnetic field refers to the combined magnetic field resulting from the contribution of multiple magnetic sources in a given space. It is calculated by summing up the magnetic fields generated by individual sources or components present in the region. The net magnetic field's strength and direction can vary depending on the orientation and magnitude of the contributing magnetic fields.


What is uniform and non uniform magnetic field?

A uniform magnetic field has constant strength and direction throughout the region. A non-uniform magnetic field varies in strength or direction in different parts of the region. Uniform magnetic fields are simpler to work with mathematically, while non-uniform magnetic fields can lead to more complex behaviors in magnetic materials.
