This a housing or stand that holds the magnetic compass assembly securely on the ship's bridge or designated location.

What do you call the angular difference between the true north and magnetic north?

This theory is based on the concept of magnetic fields generated by moving electric charges.

This is a fixed reference line on the compass bowl or card.

The difference between the compass heading and the true heading should not exceed by how many degrees?

This is usually printed on navigational chart along with its annual rate of change at the time of publication.

This are small magnets placed near the compass bowl to compensate for the ship's magnetic deviations.

This is a circular housing that contains the liquid in which the compass card floats.
