A magnetic field is the invisible field of magnetic force that is exerted on substances that are sensitive to magnetism. Magnetic fields have been studied by scientists and are used in applications such as compasses and MRI equipment.
Magnetic fields are bascially lines of force caused by magnetic poles. It is invisible, but you can track how the field lines are formed doing a small experiment. Spread some iron fillings on a tray. Then bring a magnet up close to the iron fillings but not too close. You can observe that the iron fillings move into the field lines of the magnet that you brought up close. That's a miniature of a magnetic field. The earth's magnetic field is much bigger.
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

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.
rocks with magnetic fields that point south have
Magnetic Fields - album - was created in 1981-05.
A magnetometer detects magnetic fields.
Yes; if the storage is on magnetic media then that can be altered by magnetic and electric fields.
