Question

Explain the construction of a compass n its uses

Answer 1

It functions as a pointer to "magnetic north", the local magnetic meridian, because the magnetized needle at itsheart aligns itself with the horizontal component of the Earth's magnetic field. ... The needle is mounted on a low-friction pivot point, in bettercompasses a jewel bearing, so it can turn easily.

· A magnetic rod is required when constructing a compass. This can be created by aligning an iron or steel rod with Earth's magnetic field and then tempering or striking it. However, this method produces only a weak magnet so other methods are preferred.

Regardless of their intended purpose or the complexity of their construction, most mechanical compasses operate on the same basic principle. A small, elongated, permanently magnetized needle is placed on a pivot so that it may rotate freely in the horizontal plane.
