Magnet

A holding magnet is a device that creates a strong suction force to attract and secure metal objects right where I need them. I use these magnets whenever I want to keep something in place—whether that means lifting heavy metal sheets in a factory or snapping a cabinet door shut at home. They play a…

Halbach Arrays are special arrangements of magnets that focus almost all magnetic force on one side, leaving the other nearly field-free. I find this design fascinating because it solves real problems in industry. With Halbach, manufacturers get a stronger magnetic field where they need it, cut down on wasted energy, and make machines lighter and…

Magnetic coupling uses magnetic fields to transfer force and motion without physical contact. I find that this method prevents wear and eliminates the need for seals, which sets it apart from mechanical couplings. Neodymium magnets play a vital role in modern designs. Their strong fields, compact size, and resistance to demagnetization ensure reliable performance, even…

No, magnets—even strong neodymium magnets—are not inherently bad for batteries. If you’ve ever wondered, “are magnets bad for batteries?” the answer is no. I often hear concerns about whether magnets can drain, damage, or compromise battery safety, but in my experience, the main risks come from physical impacts rather than any interaction with battery chemistry….

Are batteries magnetic? Most batteries do not show magnetic properties. Some batteries stick to magnets because of their steel casings or certain internal metals. I check the battery type and casing to know if it reacts to a magnet. Strong magnets, like those from Osenc, may affect battery safety in rare cases. I always handle…

You would find answers to most of the usual questions people ask about magnets and magnetism, about the history of magnetism, magnetic materials, magnetic properties, magnetic orientation, magnetic poles, and others. To learn more technical details regarding these aspects, have a look at our Magnetics-101-Design Guide. Request a quote or call us today and see…

You demagnetize a permanent magnet by messing up the alignment of its magnetic domains. If you ask, “how do you demagnetize a permanent magnet,” you can heat it, hit it, or use an alternating current. Each way changes how the magnet acts. When you ask, “how do you demagnetize a permanent magnet,” always look at…

A permanent magnet is a material that makes its own magnetic field. This happens because the electrons inside it line up in a special way. I use permanent magnets every day in many ways. In some metals, like iron, cobalt, and nickel, the electrons spin and move in a way that lines up. This makes…

When I first started in the industry, I was told I needed an IATA Report while working on air freight. Recently, a friend wants to join my industry, and yesterday he asked me what an IATA Report is. After checking the latest information yesterday, I wrote an article specifically to help you. What Is The…

In factories, a magnetic drum is a machine used to separate magnetic metals like iron from other materials. As the drum spins, it pulls out metal pieces using a strong magnet. This helps protect other machines and makes the final product cleaner and safer. Magnetic drums are commonly used in recycling, mining, food processing, and…
