An electrical machine (1) operating by switching of magnetic flux comprises a first magnetic structure (10), a second magnetic structure (20) and a winding (30). The first and second magnetic structures are arranged movable relative to each other along a predetermined motion path (4) and have respective sections (12,22) interleaved with each other via more than 4 air gaps. The first magnetic structure presents at each air gap a variable magnetic permeability. The second magnetic structure presents at each air gap a variable magnetic permeability and/or permanent magnet poles. Magnetic periodicities of the first and second magnetic structures are equal. For each of the air gaps, most of the magnetic flux passes at each instant in the same direction. The winding has a respective loop (32) provided either around respective section in the direction of the predetermined motion path, or along respective section along an entire closed predetermined motion path.
