Science Tuesday – What Keeps Moving Magnetic North and the Continents

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.
