Three things:
The magnetosphere, most specifically the Ionosphere.
vacuum or trough
Your magnetic compass does not actually point north, it merely aligns itself with the lines of magnetic force at your location. These do not necessarily point to the North - they may differ by some tens of degrees. This difference is the Magnetic Declination. On hikers maps, you'll find that the true north of the map is shown as well as the magnetic declination at that region. The declination itself changes slowly, too slow for you to bother with its changing.
During Metaphase the protein strands that attach to the centromere region are called spindle fibres.
All atoms consist of two regions. The nucleus is a very small region located near the center of an atom. In every atom the nucleus contains at least one positively charged particle called a proton and usually one or more neutral particles called neutrons. Surrounding the nucleus is a region occupied by negatively charged particles called electrons. This region is very large compared with the size of the nucleus. Protons, neutrons, and electrons are often referred to as subatomic particles.
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.
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.
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.
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.
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.
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 .
A Magnetic Force
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.
That is called its magnetic field.
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.
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.
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.
