It means that the planet generates a large magnetic field in its interior. Astronomers explain this using the "dynamo model". This predicts a magnetic field when there is a rotating electrically conducting liquid inside the planet. However, there are several ways this can happen and the theory is complicated. It is pertinent to us because if a planet has a weak magnetic field, it is more susceptible to cosmic radiation, high doses of which can kill us.

What is the most powerful planet?
Jupiter. I mean it has the strongest gravitational field. It has the greatest magnetic field as well.
Do other plants have magnetive line?
I assume you mean "planets". Yes, other planets have magnetic fields, too. Jupiter, for example, has a very strong magnetic field.
What is the space all around a magnet called?
I'm sure you mean the magnetic field
What do you mean by magnetic?
Terrestrial magnetism is the study of magnetic field on earth.
What is the unit of the magnetic field?
the unit of magnetic field is tesla (si unit ) and gauss (cgs ) unit.1 tesla = 10,000 gauss .1 tesla= 1N/mAAnswerIt depends on what you mean by 'magnetic field'. If you mean 'magnetic flux', then the SI unit is the weber(pronounced 'vay-ber'). If you mean 'magnetic flux density', then the SI unit is the tesla. If you mean 'magnetic field strength', then the SI unit is the ampere per metre.
If magnetic lines are close what does this mean?
If magnetic lines are close, then the magnetic field has a lot of magnetic lines of force packed together. This translates into a large number of flux lines per unit of area through which they're passing. A large number of flux lines per unit area means a high field density. High flux density means the magnetic field is strong compared to a field where the flux lines are not as close together.
What does de-magnetised mean?
lost its magnetic field.
Earth's magnetic field is believed to be generated from what region?
If you mean the region of influence of the earth's magnetic field then its called the earth's magnetosphere
What is a electronic and magnetic?
It depends what you mean, but.... ---- Magnetic ---- it could be when you make something magnetic, or when the magnetic field of a magnet attracts a piece of Iron or steel
What does the presence of a magnetic field on Earth compared with other terrestrial plants indicate?
Plants don't have a significant magnetic field. Perhaps you mean "planets"?
Why are there magnetic strips on the ocean floor what do they mean?
The earth maintains a magnetic field due to the metals that make up its core. Thus, all rocks are influenced by this magnetic field and "face" the direction the field is "facing". Every few hundred million years the poles switch, and with it the magnetic field. Similarly, all rocks "face" the new direction. Magnetic strips are indicators of when the magnetic field of the Earth changed.
What does magnetic mean in science terms?
A magnetic field is a field of force produced (1) by moving electric charges, (2) by electric fields that vary in time, and (3) by the intrinsic magnetic field of elementary particles associated with the spin of the particle.
