  1. Halbach Array for Electric Motors

    Halbach Array for Electric Motors
    Let’s talk about the Halbach Array. A phenomenon that was initially discovered in 1973, this arrangement of permanent magnets functions to make the magnetic field one side stronger while negating the opposite field to nearly zero. For comparison, with a single magnet, you will have equal strength on either end. It wasn’t until the 1980s that a physicist applied the Halbach array as a means to focus particle beams, electrons, and lasers.  Continue reading →
  2. Permanent Magnets for Different Kinds of Sensors

    Permanent Magnets for Different Kinds of Sensors
    Permanent magnets are used in a variety of sensor applications; but what exactly is a sensor? A sensor measures input from its environment and converts it into data. That data might be collected and interpreted visually by a person (e.g., glass thermometer), or electronically by a machine. Sensors measure all sorts of things, including distance, weight, temperature, proximity, position, velocity, direction, etc.  Continue reading →
  3. Is it Time to Replace Your Magnet?

    Is it Time to Replace Your Magnet?
    If well-cared-for and left unexposed to external influences, a permanent magnet will stay strong for a very long time. When in use, it’s a slightly different story. Regardless of how you’re using your magnets, but certainly, in business and industrial applications, it’s important to know what can weaken a magnet so you can replace it as necessary. Replacing your magnets at the most appropriate interval is an important way to protect the value of your investment.  Continue reading →
  4. What Are “Air Gaps” & How Do They Impact Magnets?

    What Are “Air Gaps” & How Do They Impact Magnets?
    There are many factors to consider when purchasing magnets for your business. You must consider the size, shape, pole strength, magnetization direction, etc. One important factor that is often overlooked is the air gap.  What exactly is the “air gap?” Continue reading →
  5. Magnet Storing Tips, According To Magnet Type

    Magnet Storing Tips, According To Magnet Type
    Magnet safety entails how to handle magnets, where to store them, and the ideal storage environment. It is especially important when handling strong industrial magnets. If magnet safety is not followed, it can lead to personal injury or damage directly to the magnet, such as breaking, chipping, and cracking. Continue reading →
  6. Three Ways To Use Industrial Magnets On Cruise Ships

    Three Ways To Use Industrial Magnets On Cruise Ships
    In a recent blog post, we shared three magnetic hacks to upgrade your cabin, such as using hook magnets to hang items or clip magnets to organize your stateroom. Similar to these hacks, there are many cruise ship hacks on an industrial level.  Because magnets can have a strong pull force, are weather-resistant and durable, and maintain their properties both indoors and outdoors, they are ideal to use on cruise ships. This is largely because many walls and surfaces are magnetic.  Continue reading →
  7. Magnets and Chicken Nuggets — The Crossover You Never Knew You Needed

    Magnets and Chicken Nuggets — The Crossover You Never Knew You Needed
    Magnets and chicken nuggets — What could be more well-loved? But do you know the connection? Magnets have long been critical in the food industry, helping with sorting and separating any metal scrap away from product, but they’re also involved in research and testing related to food quality and consistency. We’re not just talking about any food, but chicken nuggets specifically. Continue reading →
  8. Recycling & the Importance of Separating Ferrous from Nonferrous Metals

    Recycling & the Importance of Separating Ferrous from Nonferrous Metals
    If you have kids, then you’ve probably seen Toy Story 3. In a fun twist, it actually includes a little bit of magnet education. Near the end, the toys are trapped on a conveyor belt in a scrapyard. They escape the shredder by hanging onto bits of ferrous metal and getting pulled up and out by the magnetic separator. While there are certainly some finer points they glossed over, it’s a fun way to introduce kids to how magnets are used in the recycling industry.  Continue reading →
  9. Magnetic Yokes Used for Particle Inspection

    Magnetic Yokes Used for Particle Inspection
    Permanent magnets are commonly used in magnetic yokes. This refers to a handheld magnetic device used to induce a field in an area between two poles. They can also be electromagnetic yokes. Either kind of magnetic yoke can be used for participle inspection outdoors, in hard-to-reach places, or in remote locations. They can also evaluate whether a weld job is of quality, detecting surface and subsurface cracks and defects in ferromagnetic material.  Continue reading →
  10. Magnetic Chutes Used in the Many Industries, Including the Spice Trade

    Magnetic Chutes Used in the Many Industries, Including the Spice Trade
    Previously on our blog, we’ve discussed how magnetic chutes are used in animal feeding; however, they’re utilized in many other scenarios as well. For instance, magnetic chutes are also used to trap and separate iron particles mixed with powders, granular materials, or otherwise dry materials. Typically, the material is flowing freely through the chute; that means no sticky substances! Connected to a larger series of ducts, the chutes use magnets to attract iron contamination as it flows. The largest magnet is almost always placed in a hinged door that can be accessed from the outside, allowing for manual cleaning and particle removal.  Continue reading →
