Eriez Magnetics Europe claims its Suspended Superconducting Electro Magnet is the strongest suspended magnet ever built. This SSE Magnet will be used by China National Coal Industry Group at the Qingdao Port in the Huangdao District of Qingdao City, China. The Magnet will be udes to remove ferrous metal contamination present in the coal, such as detonating caps.

The SSE magnet system features a cryogenic superconducting magnet placed in a sealed vacuum enclosure incorporating two Cryo-cooler heads and a recycling liquid helium reservoir. This results in the coil temperature being maintained below 4⁰ Kelvin and the magnet provides a field intensity of 4,000 Gauss at a suspension height of 550mm.
