Microwave Electromagnets: The Ultimate Tool for Handling Sheet Metal
A DIY enthusiast has created an electromagnetic sheet metal handler using the transformers from old microwave ovens. The open-frame electromagnets, when energized with a battery from a Ryobi cordless tool, can stick to sheet metal. The creator built a prototype and then a more polished version, which was 3D-printed from lime green filament. The video shows the design and build, as well as field testing.
