The first proportional compasses were invented in the mid sixteenth century. Galileo invented a geometric and military compass in Padua in 1597. With his compass it was possible to make all sorts of arithmetical and geometrical calculations, from calculating interest to square and cube roots to drawing polygons and surveying.
Muslims use specialized compasses for locating the direction of Kabatullah (the Ka'aba in Mecca) at the time of offering Namaaz (Prayer/Supplication).
It is an expression, not an equation and so cannot be proportional nor non-proportional.

The first compass was invented around the year 1044. Modern liquid magnetic compasses stem from the mariners compass that was invented in Europe around 1190.

The compass was first used by Chinese and Mediterranean sailors in about the 1000's or so. The exact date when the compass was first invented is not known precisely. These first compasses were usually pieces of magnetic iron floated upon pieces of cork or straw in a bowl of water. With heavy iron and steel ships became precedent during the 1800's the use of lead compasses became pretty much obsolete, for this reason the gyrocompass was invented.
The plural possessive for compasses is compasses'.
Magnets were not invented, they were discovered. Naturally occurring magnets called Lodestones have been known and used in compasses to navigate for thousands of years.
There are two main types: Magnetic compasses and gyro compasses.
A magnetic compass was first used by the Chinese Han Dynasty.
The possessive form of compass is compass's.
It was invented by the Chinese people in the Qin dynasty (221-206 BC). They made these early compasses with a mineral that aligns itself the the earth's magnetic field called lodestone.
No. compasses use a complex spinner.
