Description
This can be used to easily distinguish the polarity of magnets.
It requires three circular magnets each with a diameter of 5mm or 6mm (or more). When installing, the three magnets should be arranged in the order of NS SN NS. This way, the repulsion between the magnets will make them stay firmly in the printed part (as shown in the figure below), which can be suitable for magnets of different thicknesses.
Attached is a method to distinguish the magnetic poles of a magnet: use a thin line or other soft object (I use a tissue) to lift the magnet. When the magnet is stationary, the end pointing towards the North Pole of the Earth is the North Pole (N), and the other end is the South Pole (S). You can use the compass function on your phone.
