Compasses

This apparatus is composed of a magnetized needle that rotates on an axis and marks the north-south magnetic poles, so that it indicates the magnetic north and not the geographic north (since, as has been said, it is the terrestrial magnetism that makes so it works).

Based on terrestrial magnetism, this instrument is useless at the North and South Poles because the lines of force of the Earth's magnetic field converge there. However, since time immemorial it has been a very useful instrument for orientation, which competes today with other systems such as GPS, but it differs from them by the advantage of its portability and autonomy (since it does not require energy electric to work and can therefore be used anywhere).
