Brookhaven National Laboratory (BNL) is dedicated to answering basic and applied science questions that range “from the birth of our universe to the sustainable energy technology of tomorrow.” Recently, they announced the construction of a test accelerator they call the “Energy-Recovery Linac,” or CBETA, at Cornell University.
The CBETA will reportedly recycle energy by intertwining particle beams through chains of multi-pass permanent magnets in a Halbach array, which augments the magnetic field on one side and cancels the opposite field to near zero. This would revolutionize accelerator science, helping to reduce both cost and size, and fusing the best traits of linear and circular accelerators. Continue reading →
In a breakthrough toward the effort for fusion energy, scientists are using powerful new magnets in order to build the world’s first energy-producing fusion experiment. In a report published by the American Physical Society, it was revealed that collaborating scientists from the Massachusetts Institute of Technology's Plasma Science & Fusion Center and Commonwealth Fusion Systems are working to speed up the development of fusion energy that can help fight the harmful effects of climate change. But how?
The methodology behind the experiment is based on high-powered temperature superconducting magnets. Continue reading →
Most of the magnets we encounter on a regular basis—the ones on our kitchen refrigerator or used to hang something from the ceiling—are very manageable as they fit comfortably in your hand. There are many more powerful magnets out there, however, that are smaller than a penny. Though this makes them harder to handle with your bare hands, they’re extremely useful for certain applications. Continue reading →
Every type of rare earth magnet, whether neodymium, AlNiCo, or something else, has its own alphanumerical system for classifying strength. Each one is unique, and there’s no simple formula for translating a system from one magnet type into the system for another. Continue reading →
When you imagine the contrast in magnetic strength between the business card magnet on your refrigerator and something like a rattlesnake egg, it’s clear that not all magnets are equal. For an industrial application, choosing the correct magnet is crucial to the proper function and efficacy of that application.

Air travel can be a real headache. Before even taking off, there are so many steps to complete and account for. Gathering boarding passes, getting through security, finding the right terminal, and waiting at the gate all add up to a rather hectic and draining experience. On top of all this, Earth’s magnetic field is creating a new problem for runways around the world. Continue reading →
2016 has certainly been a newsworthy year, and magnetism didn’t miss out. It seemed like every time we turned around, magnets were popping up somewhere in the world (or galaxy). So as the year draws to an end, we thought we’d take a look back on some of the most exciting and interesting pieces of magnetic news. Continue reading →
We’ve been there: You’re perusing Pinterest or browsing blogs when you catch a project that you absolutely must make. Maybe you even saw it on our magnet blog! You hit the purchase button to get all the supplies you need and a few days later, a box arrives at your door. It’s time to jump right in and make the gorgeous, Instagram-ready project you’ve been dreaming of, right?
Hold on there, sailor, because we’ve got some news for you: While your magnets can be useful and educational, they also have a few limitations. If you find yourself making any of these magnet mistakes, you may actually damage your magnets. Continue reading →
