Abstract
An electromagnetic stabilizer includes a first and a second plurality of electromagnets aligned along a transversal direction orthogonal to a feeding direction of the strip. The first and second plurality of electromagnets are mutually arranged in a position mirroring the theoretical feeding plane. Each of the electromagnets includes: a core provided with at least a first and a second pole; a first and a second coil wound about the first and second poles, respectively; two power sources to supply the coils, respectively, so as to generate a first and a second magnetic field, respectively; and at least one concentrator made of ferromagnetic material connected to the core and arranged so as to make the first and the second coil magnetically independent of each other.
