This is perhaps the most important part. In a regular compass, the needle always points north. To replicate this, we must change the polarity of the material and rearrange the order of the atoms of the needle by magnetizing it to point north.
Place your magnet on a flat surface (table) and slowly pull the needle across it on the north side of the magnet. To get any effect, you must repeat this at least 20-60 times. You get more of an effect if you repeat the step more, for example, 100 times is better than 50.
