A magnetic field demonstration vividly illustrates the invisible forces at work around magnets. By using simple materials such as a bar magnet and iron filings, one can sprinkle the filings over a sheet of paper placed atop the magnet. The iron filings will align themselves along the magnetic field lines, making the otherwise invisible field visible. This demonstration effectively shows how magnetic forces extend in space, creating a pattern of curved lines that represent the direction and stren
