Boussole - 10 things to know with detail

• A compass, also known as a boussole in French, is a navigational tool used to determine direction relative to the Earth's magnetic poles.
• The basic design of a compass consists of a magnetized needle that aligns itself with the Earth's magnetic field, pointing towards the magnetic north pole.
• The magnetic north pole is not the same as the geographic North Pole, which is the point where the Earth's axis of rotation intersects its surface.
• Compasses come in various types, including traditional magnetic compasses, liquid-filled compasses, and digital compasses that use sensors to determine direction.
• Compasses are commonly used in outdoor activities such as hiking, camping, boating, and orienteering to navigate and find direction.
• In addition to outdoor use, compasses are also used in various industries such as aviation, marine navigation, surveying, and military operations.
• Compasses are calibrated to compensate for magnetic declination, which is the difference between true north (geographic North Pole) and magnetic north.
• To use a compass, one must hold it level and steady, allowing the needle to settle and point towards the desired direction.
• Compasses are often combined with maps to determine a specific bearing or direction to reach a destination accurately.
• The invention of the compass is believed to have originated in ancient China during the Han Dynasty (2nd century BC) and later spread to Europe in the Middle Ages, revolutionizing navigation and exploration.
