Making an electromagnet is as simple as wrapping some wire around a nail and taping the wire to both ends of a battery. When you’re done, you can pick up some paper clips – it demonstrates the concept ...

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 ...

Ziad Melhem outlines the thinking that went into the design and development of the world’s most powerful all-superconducting magnet All together: The 32 T magnet lowered into its cryostat. (Courtesy: ...

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 ...

Little Big Coil: the record-breaking magnet is the size of a toilet roll core. (Courtesy: Stephen Bilenky/National MagLab) The highest continuous magnetic field ever created in the lab has been ...

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 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 ...
