Magnets are common items in our daily lives, from refrigerator magnets to headphones and electric motors. But have you ever wondered why magnets can attract metals such as iron, nickel, and cobalt, but not copper, aluminum, or plastic? The principle behind this involves the movement of electrons in the microscopic world and the magnetic properties […]

MagSafe technology has revolutionized mobile device charging since its 2020 relaunch, with 87% of iPhone 15 users reportedly owning at least one MagSafe accessory. However, improper magnet selection can lead to: Safety risks: Weak adhesion causing device drops (12% of accessory returns linked to magnetic failures) Performance issues: Charging speed reduction up to 40% from […]

We often see a variety of magnets, which are made of different materials and have different scopes of use. The following is the classification and characteristic analysis of the main product types. Neodym Magnet Neodym Magnet other magnetic materials, Neodym Magnet has outstanding magnetic performance advantages, with high remanence (Br), high intrinsic coercivity (Hcj) and […]

Demagnetizing permanent magnets is essential in industries where unwanted magnetism causes problems. As a magnet manufacturer, we often guide clients on safe demagnetization methods. Demagnetization weakens or erases a magnet’s field. Common methods include heating, hammering, or using alternating magnetic fields. For example, heating neodymium magnets above 80°C (175°F) disrupts their atomic alignment, reducing strength. […]

Magnetic field strength is a key parameter in understanding magnets. As a manufacturer, we often need to measure it accurately. This article explains how to measure magnetic field strength and its importance. Magnetic field strength is measured using a gauss meter[1] or a tesla meter[2]. The unit for magnetic field strength is tesla (T) or […]
