The behavior of the iron filings around the bar magnet best supports the argument that a magnetic field is present around the magnet. When the iron filings align themselves along the magnetic field lines, it visually demonstrates the invisible force generated by the magnet. This provides strong evidence for the existence of magnetic fields and their influence on ferromagnetic materials like iron.
Zack places iron fillings on a piece of paper near a bar magnet. The fillings quickly move and form a pattern around the magnet. Which argument does this evidence BEST support?
