Editing Magnetic Field Viewer (section)

== Why This Works ==

All permanent magnets have a ''Magnetic Field'', which is a "force field" made by the magnetic force it generates. Magnets have positive and negative ends, and their magnetic fields travel from the positive end to the negative end. The magnetic field applies a force on other electromagnetic things, which is why two magnets put near each other will repel (same-side) or attract (opposite-side) each other. The direction of the magnetic field can be found by tracing the ''Magnetic Field Lines'', which are a way to visualize the magnetic field around a magnet.

When a magnet is placed inside the magnetic field viewer, the iron filings all line up with the magnetic field and create the magnetic field lines. This shows us what the magnetic field of the magnet looks like, and gives us a clear visual when learning about magnetism!
