The Earth's magnetic field is principally the result of electric currents generated in the mantle by its heat causing movement of this mass. A minor perturbation of this may be caused by currents derived from the Solar Wind - the flow of charged particles from the Sun. And of course the residual magnetization of local rocks will also have some effect.

Do alloy stick on magnets?
The elements cobalt, nickel and iron are all magnetic. Most alloys containing at least one of these three elements will be magnetic. For example stainless steel is very magnetic. However alloys not containing these elements is most likely not magnetic.
Is the earth's magnetic field always the same?
The earth's magnetic field is present because of the molten iron in its core. Always a little change keeps on occurring in the earth's magnetic field. Although the change is very little with respect to time,but it is considered one of the major factors for the end of this world.
What are the elements of design?
The elements of design are the building blocks of design in any field. In other words, they could be applied to a two dimensional piece of design such as a poster, or in a three dimensional design of a garden. There seems to be agreement on what the basic elements are, but sometimes the opinions do vary.These are my elements of design:Point and lineShape and formTexture and patternColourValue
What was the significance of core?
Core, I am assuming, means "magnetic core memory". This was an early type of persistent memory used on early computers. You could put a core on a shelf and pull it down for use several years later, and it would still have the data in memory as it was the day you put it on the shelf. Core memory was used as permanent random-access memory on early computers A very small magnetic doughnut (a single core) would have three wires passed through it. Two wires would be used to set or read the position of the magnetic field of the particular core doughnut. A third wire was used to carry the signal if the field was reversed. All magnetic fields can be reversed by creating a nearby magnetic field at sufficient strength. Current in one of the address wires was insufficient to cause a change in the magnetic field of the doughnut core. But when both address wires carried current at the same time, the magnetic field generated would flip the field of the core to align with the field produced by the current in the address wires. When one of these tiny doughnuts switched magnetic poles a current was then introduced into the sensor wire and read as a change that might indicate a 1 or a zero. The machine would then put the core back the way it was to preserve that value stored in that memory location. All of this wiring using these very tiny doughnuts of magnetic material was difficult and cost a lot of money to produce. It was all they had for permanent storage until transistors came into common use.
Which type of map shows the three dimension of earths surface?
Topographic map
What is the three elements in this family that produce a magnetic field?
The three elements in the family that produce a magnetic field are iron, cobalt, and nickel. These elements have unpaired electrons in their outer energy levels, which allows them to align their spins and create a magnetic field.
What are the three elements that produce a magnetic field?
The three elements that produce a magnetic field are electric currents, magnetic materials, and changing electric fields. These elements interact to generate magnetic fields and are fundamental to understanding electromagnetism.
What three elements do magnetic materials contain?
Magnetic materials contain atoms with unpaired electrons, which generate magnetic moments. These moments align to produce a magnetic field. Key elements involved are iron, nickel, and cobalt due to their strong magnetic properties.
How does the earths magnetic field compare to a bar magnetics field?
The Earth's magnetic field is generated by the movement of molten iron in its outer core, creating a complex three-dimensional field that fluctuates over time. In contrast, a bar magnet has a simpler and more stable magnetic field aligned along its axis, with a north and south pole. Additionally, the strength of Earth's magnetic field is much weaker than that of a typical bar magnet.
One of the three magnetic elements?
Iron is one of the three magnetic elements, along with nickel and cobalt. These elements have magnetic properties due to the alignment of their electron spins, which creates a magnetic field. Iron is commonly used in magnets and magnetic materials due to its strong magnetic properties.
What three features do magnetic field lines show?
Magnetic field lines show the direction of the magnetic field, the magnitude of the magnetic field (closeness of the lines), and the shape of the magnetic field around a magnet or current-carrying wire.
Name at least three magnetic metals from the periodic table of the elements?
to describe earth's magnetic field, there are three magnetic elements of earth listed as under, 1. angle of declination 2. dip 3. horizontal component of earth's magnetic field

The three substance that form natural magnet are?
The three substances that form natural magnets are iron, nickel, and cobalt. These elements have magnetic properties due to the alignment of their atomic structure, which allows them to attract other materials and create a magnetic field.
Do alloy stick on magnets?
The elements cobalt, nickel and iron are all magnetic. Most alloys containing at least one of these three elements will be magnetic. For example stainless steel is very magnetic. However alloys not containing these elements is most likely not magnetic.
