What are advantages fo using dysprosium to make electric motor?
Apparently use of this element improves the performance of DC motors a bit, and is used when you need the utmost of performance from that motor. But it is rare and expensive. I fail to see why it would be used in a food mixer, except as a marketing gimmick, and a way to get a higher price. Wikipedia Dysprosium is a rare earth element that has a metallic, bright silver luster. It is soft enough to be cut with a knife, and can be machined without sparking if overheating is avoided. Dysprosium’s physical characteristics can be greatly affected even by small amounts of impurities. Dysprosium and holmium have the highest magnetic strengths of the elements, especially at low temperatures. Dysprosium has a simple ferromagnetic ordering at temperatures below 85 K. Above 85 K, it turns into an helical antiferromagnetic state in which all of the atomic moments in a particular basal plane layer are parallel, and oriented at a fixed angle to the moments of adjacent layers. This unusual antiferroma
