What Keeps Moving Magnetic North and the Continents…and Why?

Chuck Chatlynne, PhD

Anyone who has made a serious attempt to use a map and compass for orienteering has had to face the reality that the compass doesn’t really point to the north pole, but rather to the so-called magnetic north. In addition, magnetic north changes over the years; in Maryland, it’s been changing about one degree every ten years. Another factor is that the continents are moving (but much, much much more slowly — thank goodness). What creates magnetic north anyway and why DOES the compass point there? This presentation discusses these issues. It’s based on a map and compass presentation prepared for new Boy Scout adult leaders.

Chuck Chatlynne, PhD, earned his BS in Chemical Engineering from UC Berkeley, and his PhD in Chemical Engineering from Oregon State University. He did his postdoctoral work at the Technion – Israel Institute of technology. Chuck retired as an Engineer with the US Environmental Protection Agency, the US Army, and the US Air Force. Chuck, and his wife, Dr. Louise Chatlynne, have two grown children. Both are longtime volunteers with the Boy Scouts of America.
