So I did some specialized research all over sites using keywords and phrases like, "atmosphere," "magnetic field," "Mercury," "mercury's magnetic field," "iron substance of mercury," and so forth. I searched the NASA website and a few solar system books of my own, and here's my answer:
"Mercury does not have enough atmosphere to slow down meteoroids and burn them up by friction... The discovery of a magnetic field around Mercury led some scientists to believe that the planet's outer core, like Earth's, consists of liquid iron." - NASA
The magnetic field is so weak that the solar wind impinges on the surface and is absorbed. The fact that the magnetic field is so weak is due to the fact that it picks up solar wind where it is weakest. But that's not all. Creationist theories of planetary fields expect such a decrease because electrical resistance in a planet's core will decrease the electrical current causing the magnetic field. The smaller the core or greater the resistance, the faster the field will decay.
"Mercury's decay rate is so rapid that some future probe could detect it fairly soon. In 1990 the planet's magnetic moment should be 1.8 percent smaller than its 1975 value." - D. Russell Humphreys

Why does mercury have a strong magnetic field?
That's easy because it doesn't. Mercury's magnetic field is only about 1% that of Earth.
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.
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)
Which planet has craters cliffs and a weak magnetic field?
Mercury :) hope I helped!!
When was Mercury's magnetic field created?
Mercury's magnetic field was created in 1974-04.

The weak magnetic field around mercury suggests what?
upcoming magnetic reversal
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.
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.

What does Mercury's magnetic field affect?
it affects the other planets and its rotation
Which planet has craters cliffs and a weak magnetic field?
Mercury :) hope I helped!!
Which of the facts about the table can scientists use to infer that Mercury has a core made of iron?
Mercury has a significant magnetic field.
