In a rapidly evolving technical society, it has never been easier to stay active and track your health journey with ease. But before you go out and purchase the newest wearable gadget that promises to make your life easier, those with certain health conditions must consider the interactions of such technology in the presence of implanted medical devices.  Continue reading →

If you own a piece of diamond jewelry, you may be curious to know if it is a naturally occurring or lab-created diamond. Rather than pay for a jeweler to tell you the answer, why not pick up a magnet to uncover the truth?  Naturally occurring diamonds are formed when carbon deposits found deep in the earth are subjected to extreme temperatures and pressure, while lab diamonds are created using similar concepts and a little help from scientists. The majority of all lab diamonds in the world are created using two methods: the HPHT (High-Pressure High Temperature) method or the CVD (Chemical Vapor Deposition) method.  Continue reading →

Visually, you can see the evolution of the sportbike through time, with models trending smaller and sleeker. This ongoing reduction in size and weight is reflected in the magnetic technology that makes using them possible. The magnetic materials required to operate a motor and eventually a rare-earth “mini” motor have changed over time, but it’s fair to say that modern...

If you have ever looked up during the spring and fall months, odds are you have probably noticed that familiar v-shaped flock of feathered friends soaring through the sky to their summer or winter destinations. And while it is quite common to see flocks of birds painting the sky, you may begin seeing fewer and fewer due to a recent discovery about birds and the earth’s magnetic field.  Continue reading →

Do you own a hotel? While the job may not be quite as dramatic as depicted on The White Lotus (we hope), there is certainly a lot that goes into hotel management. Yes, you may have to deal with conflict among the staff or between surly customers, but the job doesn’t end there. There’s also the “silent” work, including budgeting and updating technological systems. For instance, traditional key cards use technology fueled by magnets. There may, however, come a time when you have to choose between specific magnetic technologies, so it’s important to know their pros and cons.  Continue reading →

Have you ever been in a plane, ready to take to the skies, and they tell you there’s been a delay? That’s right, they have to de-ice the plane. It may be annoying, but if you have a window seat near a wing, it can be an interesting process to observe. You may also be interested to know that magnets are usually involved.  Continue reading →

Cement and lime production are a significant part of the economy due to their usefulness for construction and civil engineering. Lime specifically is used in the steel industry, but it also makes up construction materials, certain paints, plastics, and rubber.  In the conveying process, in order to extract and separate tramp metal from cement and lime before it makes its way to the crushers, pulverizers, grinders, etc., magnetic separation equipment is required. Of course, it keeps unwanted tramp out of the final product, but it also protects machinery down the conveying line from costly damage.  Continue reading →

Researchers from the Science and Technology Facilities Council have designed a zero-power tuneable optics magnet (ZEPTO) that requires no electrical power. The magnet is now being put to the test in a particle accelerator, and if everything works as planned, the future of energy research could be changed in a number of ways. Continue reading →

For industries that move high volumes of product, specifically mining operations that separate ferrous tramp metal in a free-falling conveyor system, you’re likely to use hump magnets and half-hump magnets; however, magnetic humps are also used in the food industry and are particularly useful with products and material that clump or aggregate easily.  How Does it Work? Both designs, full...

And, we’re back! Welcome to part 2 of our industry round up. Last week, we delved into some of the industries that make use of the power of magnets, including the automotive industry, construction, and packaging. This week, we’re talking about another trio of industries — recycling, food processing, and mining. It turns out, they actually have quite a bit in common. Continue reading →
