A Magnetic Domain is a cluster of billions of atoms that have magnetic fields lines up the same way.
No, it doesn't.
Yes; if the storage is on magnetic media then that can be altered by magnetic and electric fields.
Electric fields are similar to magnetic fields, and can be "compressed" by the imposition of other electric or magnetic fields.
Yes, electric current does create magnetic fields
No

the needle points in the direction the magnetic fields wish. The gravity pulls the compass nearer and nearer the magnetic fields.
Solar wind.
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.
magnetic fields are essential to production of electricity
Paper is not affected by magnetic fields.
it is known as a magnetic domian.
No. While the two may be induced by the same cause and are related phenomena, they are not identical.
No, it doesn't.
The Earth is roughly spherical. Magnetic fields are roughly spherical at a sufficiently remote distance. For the lines of magnetic force repel each other.
