Axially magnetized. Typical
Parts were purchased for a new design. The core of this design was a tubular magnet, or a hollow cylinder, which was diametrically magnetized. The magnet measured
OD = 0.250" 6.4mm
ID = 0.100" 2.5mm
L. = 0.250" 6.4mm
Magnet next to brass #2 wood screw
A #2 wood screw was purchased to act as the axel of the spinner. To hold the screw in place a hole punch was used on a label to get a small circle of self argive paper. The small disc of paper was applied to the end of a magnet and the wood screw was slowly passed through by using a screwdriver. A nylon flanged spacer was purchased to be the tube where the spinner rotates. The flanged spacer and spinner were set on a piece of label applied to a desk surface and the spacer was rotated in order to rotate the compass spinner which returned to the same orientation each time. A video was recorded of the compass spinner's behavior.
