%X Soft magnetic electrical steel plays a decisive role in the transformation of electric into kinetic energy. However, the electric energy cannot be converted into kinetic energy without losses, so a part of the energy input is converted into heat. The heat losses should be kept as low as possible in order to increase efficiency and reduceemissions. This can be achieved through the help of targeted alloy development. Due to the large amount of non-grain-oriented electrical steel in all kinds of electric motors and generators, there is an enormous potential to significantly contribute to the energy transition and electromobility. Thus, the investigations of the NOelectrical steel dealt with in this thesis occupy an essential place. To investigate the influence of impurities in the structure of the rolled material on the magnetic properties of non-grain-oriented electrical steel, four electricalsteel alloys with different lanthanum contents were produced. Lanthanum was chosen because it is able to reliably bind off the elements that cause impurities, sulphur and oxygen, and thus positively influence the properties of the material.
