Dynamo generation in Mercury

Abstract

Observations during the most recent encounter of the planet Mercury by Mariner 10 seem to have confirmed the existence of a small but intrinsic magnetic dipole of about 3 × 10^(−3) gauss R_M^3, where R_M is the radius of Mercury. This field may be small enough to have a non-dynamo explanation, but it is nevertheless of interest to examine whether dynamo generation is possible for the present Mercury.
