Summary

Description
English: The magnetic field of a bar magnet revealed by iron filings on paper. A sheet of paper is laid on top of a bar magnet and iron filings are sprinkled on it. The needle shaped filings align with their long axis parallel to the magnetic field. They clump together in long strings, showing the direction of the magnetic field lines at each point.
Magyar: Rúdmágnes mágneses terének megjelenítése papírra szórt vasreszelékkel. A rúdmágnes tetejére egy papírlapot helyeztek, amelyre vasreszeléket szórtak. A tűalakú reszelékdarabkák tengelye a helyi mágneses térerősségvektorral párhuzamosan helyezkedik el. Hosszú fonalakká kapcsolódnak össze, így mutatva a mágneses erővonalak irányát minden egyes pontban.
Español: El campo magnético de un imán se manifiesta por la distribución de las limaduras de hierro alrededor de dicho imán. Una hoja de papel reposa sobre un imán y las limaduras de hierro son esparcidas sobre el papel. Las limaduras de hierro se alinean con el campo magnético, de forma que muestran la dirección de las lineas de campo magnético en cada punto.
