Parts of a magnetic compass - Video

This is a video recording showing a magnetic compass and its parts (compass bowl, soft iron and hard iron corrector). I have previously put up a video showing the parts of a compass in pictures only. But I thought I will try something new today.
Contents of this video will benefit mariners preparing for exams (written and oral examinations).
Mariners will also benefit by watching the following videos:
