information about magnets

Ever wondered what it takes to lift a manhole cover? Well, if you’re not a Teenage Mutant Ninja Turtle, and you don’t want a serious injury, then it takes a certain amount of leverage or magnets. In this blog, we’re going to cover two different methods used to lift manhole covers, what kinds of magnets are used to make the second, and a low-budget option to retrieve lost tools that slip down, down, down into the sewer.  Continue reading →

Have you ever passed a group of enormous wind turbines and wondered how they work? Aside from wind to turn their fan blades, turbines don’t require a lot; however, they’re highly complex. One thing they do require is strong, permanent magnets like neodymium magnets.  Continue reading →

Permanent magnets are a staple of the aerospace industry. They’re primarily used in aircrafts’ electric actuation systems. In other words, permanent magnets — namely neodymium magnets — are used in the motors of these driving systems, such as braking, flight control, environmental control, oxygen production, and fuel.

Magnetic drive pumps are used to move fluids in all sorts of industries. They are the reliable option, regardless of what you’re pumping. As a seal-less technology, they include a drive magnet and inner magnet connected to an impeller to push various fluids through the pump.  Magnetic drive pumps prevent leakage, saving you the loss of costly liquids. On a more serious note, if you’re pumping more dangerous liquids, pumps help you prevent damage and injuries. This is especially helpful for businesses because EPA requirements are stricter than ever before. These pumps allow for zero fugitive emissions. They may even save time on maintenance and replacement due to leaks.  Continue reading →

No matter the size of your business, magnets can be a powerful tool in your marketing strategy. You can use them to promote products and services in target areas, offer them as merchandise, or provide them as a free gift with purchases.  Continue reading →

In a recent blog, we talked about the role of magnets in land surveying and mapping; this week, we’re covering the fascinating world of hydrographic surveying. Similar to land surveying, the goal of hydrographic surveying is to determine the depth of the water and the topography of the bottom of say, a lake or ocean. The civil engineers who partake in these surveys use similar tools as they would above ground — in this case, a magnetometer with a magnetic sensor.  Continue reading →

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 →

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 →

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 →

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 →
