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.
What creates a planet's magnetic field?
The dynamo. For terrestrial planets, the dynamo is a molten core of nickel-iron. Mercury and Earth have fairly strong dynamos and therefore fairly strong magnetic fields. Venus and Mars do not, and have only weak magnetic fields.
Is mars magnetic field strong or weak?
no mars magnetic field is not strong because it is far away from the sun than earth.
Can Mercury be magnetized is it attracted to magnets?
Mercury at normal temperature and pressure is a liquid and will not hold a magnetic field - so it cannot be magnetized.
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)

When was Mercury's magnetic field created?
Mercury's magnetic field was created in 1974-04.
Why is Saturns Magnetic field strong?
more fluid = stronger magnetic field.
Is there a magnet field on the planet mercury?
Mercury does, despite its small size, have a magnetic field, and the planet is approximately a magnetic dipole (meaning the field has only two magnetic poles). Data from the space probe Mariner 10 led to its discovery in 1974, at which time the probe measured the strength of the magnetic field to be about 1.1% of that of earth, but it's strong enough to divert solar radiation and therefore creates a magnetosphere around the planet.

The weak magnetic field around mercury suggests what?
upcoming magnetic reversal
Is mars magnetic field strong or weak?
no mars magnetic field is not strong because it is far away from the sun than earth.
Which planets do have a magnetic field?
Neptune, Uranus, Saturn, Jupiter, and Earth all have magnetic fields. Mercury has a very weak magnetic field.
Can Mercury be magnetized is it attracted to magnets?
Mercury at normal temperature and pressure is a liquid and will not hold a magnetic field - so it cannot be magnetized.
How ferroelectrics are different from ordinary dielectrics?
ferroelectrics have strong magnetic field and also magnetic susceptibility & permeability value are strong (>1) but dielectric have feebly magnetic field & it have lesser value.
What planet has craters cliffs and a weak magnetic field?
Mercury
What is the benefit of the planet Mercury magnetic field?
there is no benefeit. its a myth.
