A magnetization is placed under a piece of paper. An amount of iron filings is dropped above the paper. Then, the iron filings are attracted by the polars of the magnetization and the magnetic lines are created. Finally, we observe that the direction of the magnetic lines depends from the polarity of the magnetization. The lines are directed from the north pole, to the south one.
