A Perspective of the Induction Studies in South Western Nigeria

Abstract

Employing the finite difference technique the concept of a secondary inducing source field at an altitude between 180 to 350km in south western Nigeria has been examined. The study compared numerical results with field results obtained by ONI and AGUNLOYE (1976) at Ibadan, Okitipupa and Igbanke. At both Ibadan and Okitipupa the numerical results tend to support the presence of a secondary inducing source field at 210 km and 320km respectively, while the secondary inducing source height at Igbanke was found to be closer to that of the equatorial electrojet.
