Comma magnet

This model is restricted by licensing terms. 

A simple comma sign with a magnet do demonstrate the "comma shift" (in Germany we use comma as the decimal separator) while multiplying or dividing with powers of ten for my 5th grade students.

The dimensions are ~55×38×15 mm.

It requires one 10×2 mm magnet.
