about 10 times the size of the sun
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.
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.
Saturn has a weak magnetic field compared to other planets like Earth or Jupiter. Its magnetic field is primarily generated by the motion of its metallic hydrogen interior. The magnetic field is not well-aligned with the planet's rotation axis, causing irregularities in its magnetic environment.
Jupiter's magnetic field is caused by the flow of electrically conducting material in its metallic hydrogen layer. As Jupiter rotates, this material generates a magnetic field. The combination of the planet's rotation and its metallic hydrogen layer results in its strong magnetic field.
Earth's magnetic field (and the surface magnetic field) is approximately a magnetic dipole, with the magnetic field South pole near the Earth's geographic north pole (see Magnetic North Pole) and the other magnetic field N pole near the Earth's geographic south pole (see Magnetic South Pole). This makes the compass usable for navigation. The cause of the field can be explained by dynamo theory. A magnetic field extends infinitely, though it weakens with distance from its source. The Earth's magnetic field, also called the geomagnetic field, which effectively extends several tens of thousands of kilometres into space, forms the Earth's magnetosphere. A paleomagnetic study of Australian red dacite and pillow basalt has estimated the magnetic field to be at least 3.5 billion years old.
Jupiter's magnetic field is caused by the convection of liquid metallic hydrogen in its outer core. This creates electric currents that produce the magnetic field. Jupiter's rapid rotation also plays a role in generating its strong magnetic field.
Jupiter's moon, Ganymede, is the only moon in the solar system known to have its own magnetic field. This magnetic field is believed to be generated by a liquid iron core, similar to Earth's. No other moon in our solar system has a magnetic field.
Jupiters gravitational field strength is 25 Nkg^-1
Data collected about Jupiter's magnetic field and polar regions provides valuable insights into the planet's composition and dynamics. It helps scientists understand the interaction between Jupiter's magnetic field and its atmosphere, as well as the formation and behavior of its auroras. Additionally, studying Jupiter's magnetic field and polar regions can provide information about the planet's internal structure and its magnetic interactions with its moons.
Earth has a magnetic field weaker than Jupiter but stronger than Venus.Jupiter 4.2 gauss at the equator to 10--14 gauss at the polesEarth less than 30 microteslas (0.3 gauss) at the equator to over 60 microteslas (0.6 gauss) around the polesVenus does not have a magnetic field.
The strength of a magnetic field is typically measured in units of Tesla (T) or Gauss (G). For example, the Earth's magnetic field is around 25 to 65 microteslas. In comparison, an MRI machine produces a magnetic field of around 1.5 to 7 Tesla.

No, magnetic field lines close together indicate a stronger magnetic field, while magnetic field lines farther apart indicate a weaker magnetic field. The density of field lines represents the strength of the magnetic field in that region.
The relationship between magnetic field strength and distance in a magnetic field is inversely proportional. This means that as the distance from the source of the magnetic field increases, the strength of the magnetic field decreases.
