Polarity detector assembly kit NS Wakaru-kun
NS Detector Assembly Kit NS Wakarukun
We created a kit using cardboard and a ring magnet to make a polarity tester to check the polarity of a magnet.
No scissors or glue are required for assembly, and even children can assemble it with parental assistance, but it can also be used as a practical polarity detector.
Please use this for science experiments in classes or as a summer vacation homework to learn about mechanisms that use magnets to move.

①Main housing ②Magnetic holder ③ Shaft holder -1- ④ Shaft holder -2- ⑤Axis ⑥Ring magnet ⑦NS judged magnet |
Assemble ①.
*Assemble the side with the mold by folding it in half.
 |
 |
Make a crease on ② as shown in the picture.
*Please assemble by folding along the dotted lines.
 |
Combine parts ① and ② together so that the holes line up.
 |
 |
Make sure it is fully inserted and the holes are aligned.
 |
 |
Turn it over and prepare shaft holders ③ and ④.
 |
⑤ Fold the shaft in half, align the shaft holder with the hole in the main housing, and gently insert it.
 |
Look through the peephole and insert it this far.
 |
While holding the shaft, drop the magnet into the peephole.
 |
Insert the magnet into the shaft.
(It's a little difficult to thread, so if you have a magnet nearby, you can adjust its position to make it easier.)
 |
Finally, insert the remaining shaft holder and it's complete.
 |
Slightly crushing the tip of the shaft will make it harder to remove.

Have fun determining the magnetic poles!
