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

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

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

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

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

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,
