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 →
Have you ever wondered what happens to a magnet when it is immersed in saltwater?
Well, for one, water is considered dimagnetic – which means that it exerts a weak magnetic field, and repels other magnetic fields around it. Add salt into the equation, and the water’s magnetic field is only weakened further to the point that it ceases to have any significant effect on other magnetic fields. 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 →
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 →
Frequently for DIY projects and crafts you will need to hold magnets in place using an adhesive. But what type of adhesive works best on neodymium magnets? Most types of strong glue or even strong tape will be effective when attaching magnets to various surfaces. As long as you don’t use hot glue, which uses heat causing magnets to lose their magnetism, you can’t really go wrong with adhesives for magnets. Here are a few types of adhesives crafters can use to secure neodymium magnets in place: Continue reading →
Magnets are used in a variety of different ways. From holding notes on your refrigerator to powering industrial equipment, magnets have a diverse range of applications. You may be surprised at how often you use magnets without realizing it. Other than the cute magnets holding photos on your fridge, can you find all of the other ways magnets are used in your home? Check out our infographic to get started:

Diamagnetism is a magnetic property first discovered in 1778 by Dutch scientist Sebald Justinus Brugmans. He discovered the property while using bismuth and antimony and realized they were repelled by magnetic fields. It wasn’t until 1845 that English scientist Michael Faraday named the property diamagnetism while studying elements and compounds that exhibited negative magnetism, meaning they were pushing away from the magnet. In layman's terms, diamagnetism is a property that every element possesses, which causes a weak repulsion from a magnetic field. In contrast, some elements also possess ferromagnetism and paramagnetism, which causes them to be strongly attracted or repulsed by the magnetic field.
To show diamagnetism, you can use a DIY magnet experiment with a common everyday food, grapes, to show small repulsion when exposed to a strong rare earth magnet. This experiment will only work with neodymium magnets because of the strong magnetic field they produce. Continue reading →
