Magnetized BlocksEntry/Object ID
2013.3.52Description
As the figure shows there are four numbered blocks and a revolving numbered indicator in which one number at a time appears. When the indicator is placed over a block the number in the window of the indicator and number on the block correspond.
This is one of several "Amusemens de physique" based on the principles of the magnet. Sometimes they were used to tell fortunes, etc. An explanation of these blocks is given in volume 8 by M. Le Noir (Encyclop‚die M‚thodique et M‚tiers M‚chaniques. First volume dated 1792).Collection
