What evidence suggests that earth's magnetic field may swap around in the futurw?
Evidence from magnetic minerals in ancient rocks suggests that Earth's magnetic field has reversed multiple times in the past. These reversals are recorded in the geological record as "flip-flops" of the magnetic field's orientation. Additionally, studies of the Earth's magnetic field strength and its decreasing intensity over time support the idea that a reversal may occur in the future.
How strong is the Mercury and magnetic field compared to the Earth?
Mercury has a weak magnetic field, about 1% as strong as Earth's. Earth's magnetic field is generated by its outer core, which produces a powerful magnetic field that protects the planet from solar winds and cosmic radiation. Mercury's magnetic field is thought to be caused by its partially liquid core and is much weaker due to its smaller size and slower rotation.
The area around an object that is affected by the magnetism of that object is the?
A Magnetic Force
The region of magnetic force around a magnet is know as it's?
Magnetic field
What is the area around a magnet called?
The area around a magnet where its magnetic force is felt is called the magnetic field.
What element mainly composes the inner core of Mercury?
The fact that Mercury has a magnetic field suggests that it has a core which is rich in molten iron.
When was Mercury's magnetic field created?
Mercury's magnetic field was created in 1974-04.
What planet has craters cliffs and a weak magnetic field?
Mercury fits this description, as it has craters, cliffs (known as scarps), and a weak magnetic field. Mercury's magnetic field is only about 1% as strong as Earth's magnetic field.
Which planet has craters cliffs and a weak magnetic field?
Mercury is the planet that has craters, cliffs, and a weak magnetic field. Its surface is heavily cratered, and there are large cliffs called scarps. Mercury's magnetic field is about 1% as strong as Earth's magnetic field.
Does Mercury have a magnetic field?
Yes. It has a modest magnetic field that is approximately aligned with the planet's axis of rotation. The field is a planetary dipole, and it is though to be generated in a manner similar to the way the earth is though to generate its magnetic field - dynamo action at or around the core. The strength of the field has been estimated as approximately 1% of Earth's. (see link)
Can Mercury be magnetized is it attracted to magnets?
Yes, Mercury can be magnetized. The metal is diamagnetic, meaning it can create a magnetic field in response to an external magnetic field, but it is very weakly attracted to magnets due to its low magnetic susceptibility.

Why would we not expect magnetic fields on the moon or mercury?
You might, but that would be wrong! Mercury has a strong magnetic field.
Which planets do have a magnetic field?
Neptune, Uranus, Saturn, Jupiter, and Earth all have magnetic fields. Mercury has a very weak magnetic field.
Is Mercury element magnetic?
The element Mercury is not magnetic except at cryogenic temperatures.
The area around an object that is affected by the magnetism of that object is the?
A Magnetic Force
