Eddy current ring launcher: practice 1

This entry is part 2 of 2 in the series Eddy current ring launcher

Time for a little experimentation with high voltages. To see how well the concept of launching a ring using Eddy currents works, I wanted to do a more serious test. Just to get some feeling for its behaviour, since theory alone is a bit boring. Thus, with this first prototype, no optimisations or whatsoever are… Read More »

Eddy current ring launcher: theory 1

This entry is part 1 of 2 in the series Eddy current ring launcher

The goal of this experiment is to understand, and build an eddy current ring launcher. This video shows shows some aluminium can destruction and the launching of an aluminium ring using eddy currents. Besides that it looks cool, I want to understand the underlying process, so that it is also educational in the theoretical sense, instead of “just… Read More »
