because moon has small density and shorter radius than earth. specially density is more important for calculation of Gravity.
there are some stars that have small radius but greater Gravity. why? because they have Larger density
No, the moon does not have a global magnetic field like Earth. Some localized magnetic fields have been detected on the moon's surface, but they are much weaker than Earth's magnetic field.
Yes. Otherwise Astronauts would NOT be able to hear Mission Control on Earth (earphones / headphones rely on magnets to create sound waves). And yes, magnets work in a vacuum. Light is an Electromagnetic Wave and it travels through space.
The moon is considerably smaller than the Earth, both in diameter and in mass, and it therefore has a much weaker gravitational field. The weight of an astronaut on the moon is the result of the mass of the astronaut, which is not changed by going to the moon, and the gravitation field of the moon. A weaker gravitational field produces a lower weight.
Thermal escape of atmospheric gas is much easier from the Moon than from Earth because the Moon has a much weaker gravitational force, which means that gas particles can escape more easily. Additionally, the Moon lacks a magnetic field to protect its atmosphere from being stripped away by solar wind and radiation.
Because the moon has no magnetosphere - compasses are based on magnetic energy. == ==

The moon does have a magnetic field, but it is much weaker than Earth's. This is because the moon lacks a molten core like Earth's, which generates a strong magnetic field. The moon's magnetic field is believed to be remnants from its early formation when it had a molten core.
No, the moon is not an electromagnet. It does not generate its own magnetic field like some planets do, such as Earth. The moon's magnetic field is much weaker and is thought to be remnants of its early history.
Venus does not have a magnetic field because its rotational period is very slow. This means that if its core had a liquid metal component, it would not be moving fast enough to generate a field.
The moon does not have a global magnetic field like Earth. However, there are localized regions on the moon's surface that have magnetic properties, likely due to past interactions with Earth's magnetic field when the moon was forming.
The moon does not have a dipolar magnetic field and its external magnetic field is quite weak when compared to that of the Earth.
No. The source of earth's magnetic field is the molten inner core. The moon due to its proximity of course influences our magnetic field but it is to be considered a "weak effect".
it doesn't. There is a tidal effect due to the sun, weaker than from the moon, but due to similar causes.
The moon
The moon does not generate its own magnetic field like Earth does. The moon is considered non-magnetic because it lacks a global magnetic field that is generated by a planetary dynamo.
No because the Moon does not have a magnetic field like the Earth does. The Earth's magnetic field appears to be created by a liquid metalic out core circulating around a solid core. This works like a dynamo which creates the magnetic field around the Earth. The Moon lacks a similar core stucture. This is also the reason why the Monn has no atmosphere.A magnetic compass would not work on the moon, for the moon does not have the magnetic field that the earth has, allowing us to use this device.No, because moon does not have magnetic force like earth
