Discover how to build a simple electric train using just a copper coil, an AA battery, and disc magnets in this step-by-step ...

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 ...

Scientists have broken the record for the strongest continuous magnetic field, according to a new research paper. The National High Magnetic Field Laboratory, or MagLab, at Florida State University ...

Roland is a technology enthusiast who loves to tinker and geek out about the latest smartphones, tablets, smartwatches, and other wearables and gadgets. He aims to provide honest reviews and thoughts ...

Could magnets make the mind grow stronger? In mice at least, stimulating the brain with a magnetic coil appears to promote the growth of new neurons in areas associated with learning and memory. If ...

It’s a disgrace—98 percent of US households still cook food over crude heat like a bunch of cave-dwelling heathens. Well, the 21st century is no place for such pyromantic parlor tricks. We’ve ...
