Lifting magnets are vital to several industries including scrap yards and metal recycling, truck building, and manufacturing. While lifting magnets are strong and durable, there are some factors to consider to ensure your magnet is right for your application. If you’d like to learn more, our experts discuss several tips for choosing the right lifting magnet system in our guide below.(more…)
Today one of the most widely used industrial magnets are electromagnets because of their versatility and power-saving capabilities. Unlike permanent magnets, which have a constant magnetic field, electromagnets are only active when a power source is turned on. In most cases, the power source can vary from a generator to the motor on heavy equipment. Electromagnets changed the magnet industry for the better, but how exactly do electromagnets work? In our guide below, our experts explain how electromagnets work: the basics. Read on to learn more.
An electrical current
The primary factor that sets electromagnets apart from every other magnet is, well, electricity. An electromagnet operates based on an electrical current that surrounds a wire or coil, but not just any wire or coil. A straight wire won’t produce a strong magnetic pull, so the wire typically wraps around another rod (solenoid) made of a ferrous material to enhance the magnetism.
The solenoid and wires directly relate to the magnet’s strength
To have a reliable electromagnet, you need three components: a solenoid—or rod—a conductive wire, and a source of electricity. If you were to take one of these factors away, you wouldn’t have an electrical charge nor an electromagnet. The solenoid and wire determine the strength of the magnetic pull. If the wire is loosely wrapped around the rod, you’ll have a low to medium magnetic pull. On the other hand, you’ll get a stronger magnetic field if you wrap the wire tightly.
By wrapping a conductive wire around a piece of metal and providing electricity via a battery, generator, or motor, you’ll have an electromagnet. Though we’ve highlighted the basics of how electromagnets work here, there’s a lot more science behind their properties and capabilities. We merely spared you the physics involved, such as Ampere’s law and Biot–Savart’s law.

Magnetic separators are one of the most beneficial machines for use in industries such as pharmaceuticals, scrap yards, food processing, and more. However, if users aren’t careful, magnetic separators can also cause several different types of injuries. Continue reading to learn the top magnetic separator safety tips.(more…)
Since the 1950s, permanent magnets have proven to be an essential piece of equipment in most industries. Between their versatility and ease of use, many companies find themselves investing in permanent magnets to increase efficiency, without having to do much training, if any. However, companies must decide which type of permanent magnet they want, and most important, the material used to manufacture the magnet. Continue reading to learn the different types of permanent magnets, which one is right for you, and why your company needs a permanent magnet.(more…)
As an industrial worker or decision maker, you need the right equipment to work at your highest efficiency. Various pieces of heavy equipment help workers do their job to the best of their ability, and one of the most important machines is a crane. Whether you’re a scrapyard or working on a jobsite, crane magnets––or lifting magnets––are among the most useful attachments. Keep reading to learn some considerations for choosing a crane magnet.(more…)
Whether you’ve worked your entire life in an industry that depends on magnets or your company just began using them, you should know how to inspect and maintain your magnets. If you fail to do so, you may waste money, energy, and efficiency. Industries have found exceptional value in magnets because they offer tools for workers to be more efficient.(more…)
Several industries have accepted magnetic separation as a method to reduce metal contamination in goods. Some of these industries include manufacturing, pharmaceuticals, food, and so on. If you work in any of these industries and don’t have a magnetic separation process, you’ve come to the right place. Keep reading for some considerations for choosing a magnetic separator.(more…)
Many individuals ride trains to get to and from work or to travel long distances for business or pleasure. In addition, companies still use trains to transport freight, finished goods, and raw materials, so railroad workers must maintain the tracks to ensure that trains can travel safely. There are multiple tools that railroad workers use, but nowadays they use machinery with a few different attachments to work more efficiently and save their backs. Below, we’ll cover the different types of railroad attachments that workers frequently use on their machinery.(more…)
Several industries, such as the food and beverage, pharmaceuticals, manufacturing, and more, all need a magnetic separation process in place to avoid contamination. With that said, many organizations could largely improve their magnetic separation process simply by adding plate magnets in addition to their current magnet set up. People often ask how to know when to use plate magnets and by the end of this article, you’ll know a few signs that indicate you should incorporate plate magnets.(more…)
