An electromagnetic lifter for moving hot materials includes a ferromagnetic yoke formed by a horizontal core and two vertical polarities, coils wound around the core and enclosed in a container, a non-magnetic baffle arranged between the vertical polarities and below the container at a distance of at least 40 mm to protect the container from heat radiated by the hot material. The electromagnetic lifter also includes a first space between the container and the plurality of vertical polarities that maintains a first predetermined distance between the container and the plurality of vertical polarities, a second space between the container and the core that maintains a second predetermined distance between the container and the core, and a third space between the container and the non-magnetic baffle that allows a convective flow of air. The electromagnetic lifter also includes side spacers disposed in the first space and top spacers disposed in the second space.
