This is a fun decision making spinner that I made for work. It'll be place on top of my cubicle and will be held there with the magnets on the back.
All magnets used are neodymium.
Each triangular insert has a 3 mm by 1 mm magnet, which links up with the same sized magnet in the spinner housing.
There's a 3 mm by 1 mm magnet on the bottom center of the spinner housing and another one inside the spinning arrow. These two magnets are opposing polarities (north-seeking pole facing north-seeking pole, or south-seeking pole facing south-seeking pole) to create a somewhat levitating arrow. For this reason the arrow spins smooth and fast!
Finally, there are two 8 mm by 3 mm magnets on the bottom of the spinner housing to hold the assembly to my metal cubicle at work. Of course, none of the magnets are required for the spinner to function.
