Electromagnetic Equipment: Powering Efficiency and Automation Across Industries

Industrial electromagnets-devices generating controllable magnetic fields via electric currents-are indispensable in modern manufacturing and recycling. Their flexibility and power enable solutions where permanent magnets fall short.

1. Material Handling & Scrap Processing
   Lifting Magnets: DC-powered electromagnets handle ferrous scrap, steel plates, and machinery parts. Walker Magnetics and SGM Magnetics lead this sector, with the global scrap lifting magnet market projected to reach ¥3B (USD $420M) by 2027.
   Conveying/Sorting Systems: Electro-magnetic plates or pulleys integrated into conveyors automate metal sorting in recycling plants, improving purity and throughput.
2. Precision Manufacturing
   Clamping/Fixturing: Electromagnetic chucks provide vibration-free holding for CNC machining of steel components, replacing mechanical clamps for complex geometries.
   Forming & Joining: Pulsed electromagnets enable contactless shaping/welding of conductive materials (e.g., automotive body parts) via Lorentz forces-eliminating heat distortion.
3. Quality Control & Automation
   Actuators: Solenoids and linear electromagnets control valves, brakes, and robotic arms with millisecond precision.
   Separation Systems: High-gradient electromagnets purify non-ferrous metals, plastics, and minerals by extracting paramagnetic contaminants.

• High-Power Designs: Stangenes Industries' pulsed coils achieve 40-tesla fields for R&D and advanced material testing.
• Cooling Technology: Water/air-cooled electromagnets permit 24/7 operation in foundries and metal yards.
• Resilient Supply Chains: With 75% of rare earth processing concentrated in China1, manufacturers like MLTUS and Kanetec are diversifying material sourcing and recycling end-of-life magnets to mitigate shortages.

• Energy Efficiency: Modern electromagnets use optimized winding (e.g., foil coils) to reduce power consumption by 15–30%.
• Customization: Suppliers offer application-specific designs, such as radiation-resistant magnets for nuclear facilities.
• Lifecycle Management: Recycling NdFeB from scrapped electromagnets can cut supply chain emissions by 64%
