A magnetic field is not really made of any matter, but is more a zone or region of the influence of a magnet or movement of an electric charge. The reason something charged or magnetized passing through a magnetic field will feel a force is explained by the exchange of force carriers (with the electromagnic force, these are photons).
The Earth's magnetic field for example is thought to be created by the motion, including convection and spin, of liquid metal, mostly iron alloys, in the outer core, acting like a dynamo.

What two things does earth have in common with the outer planets?
moons and magnetic fields ;D
Can a planet have a quadrupole magnetic field?
Yes - several planets have magnetic fields that do not even vaguely resemble Earth's current 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.
How do the orientations of Uranus' and Neptune's magnetic axes differ from those of the other planets?
The magnetic fields are not aligned with the rotational axis of the planet and they are not located at the center of the planet.
Differentiate Jovian planet from terrestrial planet?
The four Jovian planets in our solar system are Jupiter, Saturn, Uranus and Neptune. The four terrestrial planets are Earth, Venus, Mars and Mercury. The difference between the Jovian planets and the terrestrial planets is that Jovian planets are enormous and made of gasses and ices while terrestrial planets are relatively small and made of rocks and metals. Other differences are that terrestrial planets have high densities, rotate slowly, have no moons or magnetic fields and have thin atmospheres (Earth is an exception because it has a moon and a magnetic field), while Jovian planets have low densities, rotate rapidly, have many moons and a magnetic field and have thick atmospheres.
Do the other planets have magnetic fields?
yes all the other planets have magnetic fields except venus because it rotates to slowly
What does magnetic fields affect?
it affects the other planets and its rotation
Do humans have a magnetic field?
No. The magnetic fields of objects such as planets are due to currents withing their molten interiors. Asteroids are completely solid and so do not have magnetic fields.
Which planet has a magnetic shield?
All planets have magnetic fields. I believe that in most cases, this magnetic field can act as a shield.
Which planets do have a magnetic field?
Neptune, Uranus, Saturn, Jupiter, and Earth all have magnetic fields. Mercury has a very weak magnetic field.
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.

Can a planet have a quadrupole magnetic field?
Yes - several planets have magnetic fields that do not even vaguely resemble Earth's current field.
Did others planet magnetic field meet the earth magnetic field?
Planets are too far from each other to have any observable interaction of their magnetic fields.
Do any other plants besides the earth have magnets in it?
Yes. They don't have actual magnets, but they do have "magnetic fields". Other planets with magnetic fields are Mercury, Jupiter, Saturn, Uranus and Neptune.
