parfait de bonne qualité. expédition rapide
quite strong
The supply consists of 36 rods magnetised length wise i.e. ends are n&s poles and 27 sperical balls which are not magnetised. The structural assembly can be done without the balls also. One can do all the designs with the rods and the balls seems to be superfluous . The provision of the balls for a design is not a very creative idea. If it is thought to represent atoms in the crystals then it might serve crystallography. But for engineering designs 63 rods fully magnetised is a better option
DONT LET THE SIZE OF THESE MAGNETS FOOL YOU, THEY ARE EXTREMELY POWERFUL. I ACCIDENTALLY LET THEM STICK TO EACHOTHER AND IT TOOK ME SEVERAL TRIES TO SEPARATE THEM WITH THE HERLP OF MY DAUGHTER. I PURCHASED THESE TO HOLD THE MOSSIQUTOE NETING BACK ON A METAL GAZEBO WE HAVE IN THE BACK YAR. IT WORKS PERFECT. I DEFINETLY RECOMMEND THESE MAGNETS
Physical quality of coating good but as expected for the price it's highly doubtful this is N50 far too weak* Don't get this review wrong it IS a strong magnet but not what you would expect from a N50 of this size.
These Magnets attract like one may expect from N50 material. Also the outside corrosion protective finish is like it should. These are good quality magnets.
ONE OF THE MAGNETS WAS ROUGH ON ONE SIDE THE OTHER ONE I BOUGHT WAS SMOOTH AND FINISHED ON BOTH SIDES. THEY STILL STICK TO ONE SIDE OF MY HAND AND TO THE OTHER ONE ON THE OTHER SIDE OF THE HAND WITHOUT FALLING OFF MY HAND
