# A conceptual model of core dynamics and the Earth's magnetic field

## Main Article Content

## Abstract

A conceptual model of core dynamics and the Earth's magnetic field is presented. It differs from previous investigations in the use of an estimated core viscosity of 2 x 10^{7} cm^{2} s^{- 1}. The simplified derivations predict the correct order of magnitude for the external magnetic field and for the westward drift of the nondipole field.

Authors who publish with this journal as of Vol. 63 agree to the following terms:

a. Authors share the copyright with this journal in equal parts (50% to the journal, 50% to the lead author), and grant the journal right of first publication, with the work after publication simultaneously licensed under Creative Commons Attribution License CC BY-NC-ND 4.0 that allows others to share the work with an acknowledgment of the work's authorship and initial publication in this journal.

b. Authors may enter into separate, additional contractual arrangements for the non-exclusive distribution of the journal's published version of the work (e.g., post it to an institutional repository or publish it in a book), with an acknowledgment of its initial publication in this journal, and a reference to this copyright notice.

c. Authors are permitted and encouraged to post their work online (e.g., in institutional repositories or on their website) during the submission process, as this can lead to productive exchanges as well as earlier and greater citation of published work and better sales of the copyright.

NOTES

This journal is one of a handful of scholarly journals that publish original scientific works under CC BY-NC-ND 4.0 - the only Creative Commons license affording absolute worldwide protection of authors' intellectual property.

**Journal of Geophysics** is published under the scholar-publishers model, meaning authors do not surrender their copyright to us. Instead, and unlike corporate publishers like *Elsevier* or *Springer Nature* which resell the copyright to third-parties for up to **$80,000** (per paper, per transaction!), the Journal of Geophysics authors share the copyright equally with this journal.

Therefore all the proceeds from reselling the copyright to third parties are shared to equal parts as well (50% to the journal, 50% to the lead author). Under the Berne Convention, this protection is an inheritable right which lasts for as long as the rightsholder lives + 50 years.

By submitting to this journal, the lead author on behalf of all co-authors grants permission to this journal to represent all co-authors in negotiating copyright sales and collecting of proceeds. The lead author should negotiate with his/her co-authors the modalities of distributing the lead author's portion of the proceeds. Usually, this is per pre-agreed percentage of each co-author's contribution to creating the copyrighted work. (more...)
