Magnetic compass
It is the most commonly used compass. It points to the magnetic north. Its magnetized needle aligns itself with the horizontal component of the Earth's magnetic field. The magnetic field exerts a torque on the needle and pulls the north end of the needle toward the Earth's North magnetic pole and pulls the other toward the Earth's South magnetic pole.
Gyrocompass
It is a non-magnetic compass. It is based on a fast-spinning disc and the rotation of the Earth. It is used to find the geographical direction automatically. A gyroscope is an important component of a gyrocompass.
Advantages
1. It finds the true north which is more useful than the magnetic north.
2. It is not affected by the ferromagnetic materials which distort the magnetic field
