Explore the fascinating world of clean energy with this step-by-step DIY magnetic generator build. Learn how everyday items ...

If there’s something more tedious than winding coils, we’re not sure what it is — possibly rolling and wrapping coins; that’s really a bother. But luckily, just like there are mechanical ways to count ...

Resistive magnets are built in-house at the magnet lab using so-called Florida Bitter technology pioneered by researchers there. Circular plates of copper sheet metal are stamped with cooling holes; ...

The Hyperloop is getting closer and closer to becoming reality, but if it is still not coming fast enough for you Dianna Cowern (aka Physics Girl) has a decent placeholder for you. It can't carry ...

A coil of wire, or solenoid, consists of a wire coiled up into a spiral shape. When an electric current flows, the shape of the magnetic field is very similar to the field of a bar magnet. The field ...
