An electromagnetic lifter for moving hot materials (MC), comprises a ferromagnetic yoke formed by a horizontal core (1) and two vertical polarities (2, 2'), lifting coils (4) wound around the core (1) and enclosed in a container (5), a non-magnetic baffle (6) arranged between the vertical polarities (2, 2') and below the container (5) at a distance of at least 40 mm to protect it from the heat radiated by the hot material to be moved (MC), as well as side spacers (7) and top spacers (8) which keep the container (5) away from the polarities (2, 2') and the core (1) respectively.
