Driving an electric current through a molecule can create a magnetic field. Yet in practice, such fields are often too weak ...

It is a common grade school experiment to wind some wire around a screw, power it up, and watch it pick up paper clips or other ferrous materials. It is also grade school science to show that neither ...

What is an electromagnet? What does electromagnetic mean? How do electromagnets work? Electromagnets use an electrical ...

Plan a route, grab some snacks, and fuel up. Engineers and scientists have been sending massive magnets from U.S. Department of Energy (DOE) national labs on cross-country road trips. Magnets are at ...

The lifting electromagnet article I posted years ago (https://www.codrey.com/electronic-circuits/lifting-electromagnet-diy/) has been more popular that it should have ...

In a landmark achievement for fusion energy, ITER has completed all components for the world’s largest, most powerful pulsed superconducting electromagnet system. ITER is an international ...

Fusion energy just had its second breakthrough in as many months. Motherboard notes an MIT- and Commonwealth Fusion Systems-led research team has successfully demonstrated a high-temperature ...

Damping vibrations is crucial for precision experiments, for example in astronomy. A new invention uses a special kind of magnets to achieve this -- electropermanent magnets. They consist of a ...

In this video, I demonstrate the process of creating a magnetic chuck, which I’ll use as an electromagnet vise. The video ...

It’s easy to think about satellites as a bunch of mini-moons, orbiting the Earth seamlessly and without any (noticeable) movement. But that’s not quite right: satellites and other spacecraft often ...
