Abstract
- Inverse dynamo theory seeks to gain information about the motion of a liquid conductor from measurements of the magnetic field in the surrounding vacuum. We consider here a highly simplified model problem, namely a steady α2-dynamo in plane geometry with an α-field varying only in the z-direction normal to the conductor-vacuum interface. Based on perturbation theory about constant-α solutions, we find as many integral conditions on α(z) as modes are present in the vacuum field. This result is corroborated by the complete solution of a special case. [ABSTRACT FROM AUTHOR]
