===Meaning===
[[File:SolarFlare1.gif|right|thumb|This animation shows a solar flare curving back to [[The Sun]] due to a strong '''magnetic field'''.]]A '''magnetic field''' is the region around a [[magnet]] that affects other [[magnet]]s or [[Magnetic Material|magnetic materials]]s.
===About Magnetic Fields===
: A '''magnetic field''' can be shown by placing a [[magnet]] under paper and then sprinkling [[Iron Fillings|iron filings ]] on the paper.
: A '''magnetic field''' is strongest at the [[poles]] of the [[magnet]].
: When a '''magnetic field''' is drawn the lines are joining extend from the north pole [[Poles|North Seeking Pole]] to the south pole [[Poles|South Seeking Pole]] of the [[magnet]]. The arrows on the field lines point from north North to southSouth.

A '''magnetic field''' is the region around a [[magnet]] in which [[magnet]]s or [[Magnetic Material|magnetic materials]] experience a [[force]].

: When a '''magnetic field''' is drawn the lines are extend from the [[Poles|North Seeking Pole]] to the [[Poles|South Seeking Pole]] of the [[magnet]]. The direction of the '''magnetic field''' is shown by the arrows on the field lines point from North to South.
: The strength of '''magnetic field''' is shown by how close together the '''magnetic field''' lines are.
: A '''magnetic field''' is strongest at the [[poles]] of the [[magnet]].
