The Earth's magnetic field is called the Magnetosphere. Loops of magnetic energy coupling the north and south pole that trap energetic subatomic particles are called the Van Allen belt.

Solar wind.
No, the limestone is not magnetic due to the magnetic fields in the stone itself.
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.
Both magnetic materials and moving electric charges induce magnetic fields.
a part of the earths structure causes it to act like an electromagnet
no
because of electrons
No. I assume you mean a magnetic compass. A magnetic compass reacts to magnetic fields; the magnetic south pole of Earth is not exactly at the geographic north pole, so at some points of the Earth's surface, the magnetic compass will actually point south instead of north. Also, a magnetic compass will be influenced by other magnetic fields, e.g., current-carrying wires.No. I assume you mean a magnetic compass.

Ancient pottery shows movement of the earth's magnetic field. Firing the pottery fixes the ambient magnetic field in the fired pottery.
Solar wind.
Magnetic fields that dot the surface of the sun are known as sunspots. Although they are hardly cool in temperature, they are much colder than surrounding areas, which causes them to be visible as darkened spots.
The Magnetic Fields was created in 1989.
Magnetic fields can be blocked. Magnetic fields cannot penetrate a superconductor, and regions can be shielded from magnetic fields using ferromagnetic materials.
Nothing. That's exactly what a compass does ... as long as it's free to turn, and there are no ferrous metals or other sources of magnetic fields nearby.
magnetic fields are essential to production of electricity
Paper is not affected by magnetic fields.
Sea floor spreading / plate tectonics. Also magnetic reversal in the past.
