The Earth's magnetic field is generated by a process called the dynamo effect, which is driven by the movement of molten iron and nickel in its outer core. Not all planets have the necessary conditions, such as a molten core and sufficient rotation, to generate a magnetic field.
What else can I help you with?
What layer of earth creates earth magnetic field?
The Earth's magnetic field is the result of electric currents in the liquid metal outer core.The outer core of the Earth is over 2,000 km thick. It sits above the solid inner core and is composed of highly conducting liquid iron and nickel. Above the outer core is the Earth's mantle.The geodynamo is the mechanism thought to be responsible for the electric current in the core and the generation of the Earth's magnetic field through the convection of conducting fluids in the Earth's core. Other planets with a molten metal core can also have a magnetic field.See related links.
Which has a stronger magnetic field a solenoid or a electromagnet?
An electromagnet typically has a stronger magnetic field than a solenoid. This is because an electromagnet uses a ferromagnetic core, such as iron, to enhance its magnetic strength, while a solenoid is simply a coil of wire without a core.
Why dont magnets attract wood?
Wood is not magnetic, so it does not have magnetic properties to interact with magnets. Magnets only attract materials that contain iron, nickel, or cobalt because these materials have magnetic domains that can align with an external magnetic field. Since wood does not contain these elements, it is not attracted to magnets.
What type of microscope uses a magnetic field magnifies up to one million times?
A scanning electron microscope (SEM) uses a magnetic field to focus a beam of electrons onto a specimen. This microscope can magnify samples up to a million times and provides detailed information about the surface topography and composition of the specimen.
What is a power field?
i dont know what a power field is. im just a 10 year old asking "Answers" for the answer. but they dont have the stupid answer. (and their name is supposed to be answers) but there name is not true because they dont have the answer

The magnetic record in the rock on the ocean floor depends on when the rock was?
The magnetic record in the rock on the ocean floor depends on when the rock was formed. When molten rock solidifies, it locks in the orientation of the Earth's magnetic field at that time. This provides a record of past magnetic field reversals and helps in studying the movement of tectonic plates.
Is Neptune's polarity like earth's?
Yes, Neptune, like Earth, has a magnetic field that is tilted relative to its rotational axis. However, Neptune's magnetic field is much stronger than Earth's and is shifted at a greater angle, making it unique in comparison.
Does the area of magnet effect the magnetic field?
i really dont know
Are the planets with rings inner or outer planets?
Only the four outer planets have rings. The four inner planets (Mercury, Venus, Earth and Mars) dont have rings.
What mf is the space around a magnet where it has an effect?
The space around a magnet where its magnetic effect can be felt is known as the magnetic field. It is a region where magnetic forces act on other magnetic materials or moving charges. The strength of the magnetic field decreases with distance from the magnet.
How can a magnet attract a piece of iron that is not magnet?
When a magnet is brought close to a piece of iron, the magnetic field of the magnet causes the atoms within the iron to temporarily align in the same direction as the magnetic field. This alignment creates a magnetic field within the iron, which then interacts with the magnetic field of the magnet, causing attraction between the two. The iron itself does not become permanently magnetized, it just responds to the external magnetic field of the magnet.
In what earth layer does out magnetic field originate?
Magnetic declination changes over time because themagnetic poles move slowly, between 1580 and 1820, for example the direction of magnetic north in London changed by 35 degrees Written by Londyn reid 13 yrs old
When do superior planets appear brightest?
Superior planets (those outside Earth's orbit) appear brightest when they are at opposition, which is when they are on the opposite side of Earth from the Sun. This is when they are closest to Earth and fully illuminated by the Sun.
How many planets away is Jupiter from earth?
i dont know you guys find the answer. lazy retards!!!!
What is the best term that describes the space surrounding a magnet in which the magnet force acts?
The best term to describe the space surrounding a magnet in which the magnet force acts is "magnetic field." The magnetic field is a region around a magnet where magnetic forces are exerted on other magnets or magnetic materials.
Is the earths gravity the same as the magnetic field if not what is the difference in effects?
i dont know its aload of bumf go away :p
