Researchers from the Masdar Institute of Science and Technology of the UAE are developing novel, low-cost magnets with improved magnetic properties that can withstand higher temperatures to replace the expensive rare-earth magnets commonly used in automotive, aerospace, military and energy industries.

Dr. Behjat AlYousuf, Interim Provost, Masdar Institute, said that the novel magnetic materials that Masdar Institute researchers are discovering could support the development of next-generation clean energy technologies, including wind turbines, and have the potential to impact many other key economic industries that rely heavily on strong permanent magnets, including aerospace and defense.

Currently, each megawatt of power generated by a wind turbine requires up to one ton of rare-earth magnets. Our research aims to develop alternative, low-cost magnets that can reduce the cost of wind turbines, said Dr. Mamoun Medraj, Professor, Materials Science and Engineering, Masdar Institute. Dr. Medraj and Post-Doctoral Researcher Dr. Ahmad Mostafa are leading this research.

Dr. Medraj believes the magnets they are developing will be significantly cheaper and have greater thermal stability than neodymium based magnets, which are the strongest rare-earth magnet used today, making them well-suited for demanding, high-temperature applications like the power and automotive industries. They also can provide the UAE with a potentially high-value product in the form of cheaper magnets.

The problem with neodymium magnets is that they are only good up to 150 degrees Celsius. After that, they demagnetize. While our magnets might not have the same amount of magnetic energy as neodymium magnets, it is more thermally stable and cheaper in price, Dr. Medraj explained.

According to a report recently published by the Royal Society of Chemistry, Neodymium demand is expected to increase by 700 per cent over the next 25 years.
