The spin axis of a gyroscope tends to remain fixed in space in the direction in which it is started. How does this gyroscope become north seeking so that it can be used as a compass?

Correct Answer: Option C — By mechanically or electrically applying forces to precess the gyroscope

A free gyroscope maintains its orientation in space. To make it north-seeking, we apply a torque—either through gravity-controlled pendulous weights or electronic sensors—that causes the gyroscope to precess. This precession forces the spin axis to align with the Earth's meridian, effectively creating a north-seeking compass.
