The attractive force of Magnetic Attachment is measured just separated point. Too many balles this JIG has. Is it not need too many, and are there interfere for the measure?

Thank you for your quesions.
Holes of lower JIG have bearing structure, and small balls are arranged in a spiral lengthwise arrangement in the holes. When the stick of upper JIG went through these arrangements of guiding small balls, a rule of a vertical direction of a tension test was enabled without frictional resistance, and, at a tension test, power of absorption only for a magnet came to be reflected by values.
