Similar to last Humphreys’ article, but this one is slightly updated, and includes visual aids such as graphs, etc.

Thanks for the ping!

In looking the first graph labeled “Mercury” if one follows the sloping line it would seem to indicate that Mercury's magnetic field should disappear entirely within a few hundred years.

But since the left hand scale is showing a exponential scale while the bottom is years in a linear scale.

Well, you see what I mean? According to the graph the lose of field would be extremely large, say 90% of total, during the first 2000 years or so of the planet's existence.

Does Humphreys or anyone else offer a mechanism by which that could occur?
