Early geodynamo work
DOI: 10.1063/1.4797301
Lathrop comments: After the first two successful liquid metal dynamos, 1 there has been considerable recent activity in experiments seeking dynamo action in less constrained flows. 2 Much initial motivation for these experiments had been the work of Martin L. Dudley and Ronald W. James 3 from 1989. It is clear now, in hindsight, that Winter-berg’s 1963 paper 4 predates these experimental attempts and much of the earlier motivating theory. His paper gives a detailed analysis of different experimental possibilities for probing dynamo action using liquid metals.
Plainly, it has been an oversight of the community to not have recognized Winterberg’s contribution before now.
