How do gyro and compass sensors work? How does a seismometer work? How does GPS work? How does the auditory system work? How do analog signals work? How does an analog speedometer work? How are satellites used for oceanography? How does a dew point sensor work?
However, a magnetic compass has a drawback: the local magnetic field can be distorted near power lines or metal structures such as bridges and buildings. This can lead to significant and unpredictable heading errors, making this vehicle navigation system unreliable. Odometry data is obtained using ...
In all cases, these must be oriented to a compass direction, while in others the sun itself is a reference point. Selected kinds include plane dials, cylinder dials, scaphe dials and ring dials. A directional dial relies on azimuth (compass direction) and on the angle of the sun as it ...
This current generates a magnetic charge, and this natural magnetism of the Earth is what makes a compass work. A compass always points north because the metal needle is attracted to the pull of the North Pole. Electromagnets All Around Us Many electromagnets have an advantage over permanent ...

By the 12th century, people had discovered that they could use lodestone to magnetize pieces of iron, creating a compass. Repeatedly rubbing lodestone along an iron needle in one direction magnetized the needle. It would then align itself in a north-south direction when suspended. Eventually, sci...
