YOUR GUIDE TO LIFTING MAGNETS In material handling operations, lifting magnets have become a popular and efficient tool for moving ferrous materials such as steel plates, pipes, and scrap metal. These devices use powerful magnetic forces to lift and transport heavy objects, eliminating the need for slings, hooks, and other mechanical lifting tools. WHAT IS A LIFTING MAGNET? A Lifting Magnet is as the name suggests, a high-powered magnet that has been designed to lift a range of ferrous materials from small heaps of scrap to large heavy blocks. Lifting Magnets are portable allowing you to use them wherever required on your site. HOW DO MAGNETIC LIFTERS WORK? Thanks to excellent weight-bearing capacities and sheer power, Magnet Lifters are operated via an on/off switch or lever. Surrounded by a rotor, the magnets produce a magnetic flux/current when they are orientated in the same direction. Note that for optimal lifting, the air between the magnet and surface should be limited, if not eliminated. Once your lift has taken place, the rotor is turned off, releasing force and therefore load. TYPES OF LIFTING MAGNET Lifting magnets are typically divided into two categories: Permanent Lifting Magnets: These rely on high-strength rare-earth magnets, such as neodymium, to generate their magnetic field. These magnets are "always on" and do not require any external power source. A lever mechanism is typically used to activate or deactivate the magnetic field, allowing the operator to engage or release the load. Electromagnetic Lifting Magnets: This type of magnet lifter uses electricity to generate their magnetic field. When current flows through a coil wrapped around a metal core, a strong magnetic field is produced. Once the current is switched off, the magnetic field disappears, and the load is released. Some versions use electro-permanent magnets , combining the features of both permanent and electromagnetic magnets. These hold the load even if power is lost but still allo
