An electrical machine includes an armature and at least one field magnet arrangement separated by a gap from each other. The armature and/or the field magnet arrangement include a plurality of coils. Each coil includes conductive body sections. The body sections of the coils are joined electrically by conductive end sections. At least one of the end sections of at least one coil of the armature is tilted in a direction away from the armature towards the field magnet arrangement and/or at least one of the end sections of at least one coil of the field magnet arrangement is tilted in a direction away from the field magnet arrangement towards the armature. The electrical machine may be used in a wind turbine to generate electrical power.
