Changes

'''Magnetic fields''', resulting from the flow of electrons in metal, impose an action-at-a-distance force on other charged particles nearby.  This means that charged metals respond to magnetic fields by changing direction, or becoming attracted to or repelled from the field.

Magnetic fields, also known as B-fields, are force fields that can be explained by [[relativistic]] effects of [[electric current]]s. Magnetic fields only exert a force on moving [[charge]]s.  According to the "right hand rule," using your right hand to indicate the direction of current, the curl of the remaining fingers indicates the magnetic field, which is always perpendicular to the current, and running in the indicated.

Scientists have speculated about the history of [[Earth]]'s magnetic field.  One group that makes use of the [[Bible]] as a resource for science suggests that the history of the [[Earth]]'s magnetic field is as depicted to the right.<ref>http://www.answersingenesis.org/creation/v20/i2/magnetic.asp</ref>
