The strength of repulsion and attraction depends on the strength of the magnetic poles.
Magnetic waves iron filings marble.
The property of attracting objects by magnetic force is known as magnetism.
Magnetic lines of force of a bar magnet shown by iron fe filings on paper.
We can t normally see magnetic fields but if you sprinkle iron filings tiny bits shaved off an iron bar with a file onto a piece of paper and hold it above the magnets you can see the field underneath.
The filings will reveal the magnetic field lines.
Iron filings are small shavings of a ferromagnetic material.
Place your magnet in a plastic bag to avoid the mess of cleaning iron filings off your magnet.
Sprinkling iron filings on a sheet of paper and bringing a magnet up close to the underside of the paper we can see that the filings line up along the lines of force of the magnetic field thus showing its contours.
That being the case iron filings are an excellent way to display the magnetic field of one or multiple bar magnets.
