The source of all magnetic fields is moving electric charge: whether it is current in a wire, unpaired electrons in an atomic orbital, convection currents in the earth's liquid nickle/iron core, plasma in the sun, etc. moving electric charge is the source of all magnetic fields.

Distance affects magnetic fields in the sense that the strength of the magnetic field decreases as the distance from the source increases. This relationship follows an inverse square law, meaning that the magnetic field strength reduces rapidly as distance increases. As a result, the influence and impact of a magnetic field weaken with greater distance from its source.
No, magnetic fields do not extend out infinitely. They have a limited range of influence, determined by the strength of the magnetic source and the medium through which the field is propagating. Beyond a certain distance, the effects of the magnetic field become negligible.
The Magnetic Fields was created in 1989.
The region around a magnet or current-carrying conductor within which the magnetic force is exerted is called the magnetic field. Magnetic fields are three-dimensional and extend infinitely in all directions from the magnetic source.
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.
electrical currents are a source of magnetic fields
Question is confused, but try this... The brain does generate electrical fields, and they do change, and since changing electrical fields always generate magnetic fields ... then YES. However ... the electrical fields of the brain are of very low magnitude and are relatively slow to change (as compared to any manufactured gadget), so the brains magnetic fields are weak and are considered minor The electric field is the source code for EEG's.
Diskettes contain magnetic material that stores data. If they come into contact with a strong magnetic source, such as a magnet, it can disrupt the magnetic fields and corrupt the data stored on the diskette, rendering it unreadable. To protect the data integrity, it's important to keep diskettes away from magnetic sources.
