Discover how to build a simple electric train using just a copper coil, an AA battery, and disc magnets in this step-by-step science experiment. Starting with basic materials, watch as we construct ...
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 ...
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 ...
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; ...
A tokamak, however, is the real deal – a scientific device that produces energy from fusion. And a large-scale version is currently being built in southern France as part of the ITER initiative. A ...
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 ...
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 ...
Why magnets sit at the heart of fusion’s next leap Magnetic confinement is the central engineering challenge for fusion power because the fuel must be heated to temperatures hotter than the core of ...
Linear motors are becoming increasingly practical for general motion. Many are used for long strokes of a few feet or more. One new design, however, where the magnets move relative to a stationary ...
