What is compass and how it
works?

A compass works by detecting and responding to the Earth's natural magnetic fields. The Earth has an iron core that is part liquid and part solid crystal, due to gravitational pressure. It is believed that movement in the liquid outer core is what produces the Earth's magnetic field.

What can mess up a compass?

Objects to avoid include wristwatches, keys, tables with metal legs or steel screws, mobile telephones and even heavy framed spectacles. Many geological formations, and for that matter, many rocks, are magnetized and can affect compass readings, as can electricity power lines.

Can a compass be wrong?

If the needle becomes sluggish and slow to settle (it may appear to stick and be out of balance) it has become partially reversed. If the 'north' arrow (usually red) is pointing to south instead of north, then your compass has become completely reversed.
