Abstract

It is described a magnet assembly (260) comprising (a) a first magnet device (362) having a first angular distribution (463) of magnetization directions resulting in a first focused magnetization producing a first magnetic focal region (463a) and (b) a second magnet device (364) having a second angular distribution (465) of magnetization directions resulting in a second focused magnetization producing a second magnetic focal region (465a). The first magnetic focal region (463a) is different from the second magnetic focal region (465a). It is further described a rotor arrangement (150) with such a magnet assembly (360, 460), an electromechanical transducer (140) with such a rotor arrangement (150), and a wind turbine (100) with such an electromechanical transducer (140).
