Two unrelated problems are discussed. In the first, the breakdown of an electric fuse is considered. It is assumed that the wire melts and the liquid pinches off in finite time. Similarity solutions close to pinchoff are sought in the longwave limit and compared with high-speed photographic images.

The second problem considers the dynamo produced by laminar flow of conducting fluid down helical pipes. Such steady flow generates magnetic field spontaneously. Animations of the fully nonlinear behaviour of this dynamo are presented, showing oscillations, quenching and reversal. Calculations are extended to two interwoven helical pipes which drive a dynamo in a wider range of Reynolds numbers.

This talk is part of the Monday Mechanics Seminars (DAMTP) series.
