It is really hard to predict the magnetic properties of certain materials. Of course, there are some materials that are obviously magnetic and they are easily remembered in the minds of many. However, now scientists are looking for even more unfound materials that are magnetic as there is some great value in these types of materials. Depending on who you are and what you might do, there is a great use case for the implementation of magnetic materials.
Key Takeaways:
- Turbines and electric cars need samarium, dysprosium and terbium, all rare earth elements, all only found in China.
- It’s been a long and tedious process, attempting to find alternatives to mining these elements that pose a threat to the Earth and to workers.
- However, the search may now go faster, as Freiburg researchers have created a computer technology for quickly assessing the potential of a variety of candidates for turbine and car magnets.
“Permanent magnets used in electric cars and wind turbines currently contain rare earth metals. Reducing the amount of these elements in magnets is important, as mining them is harmful both to health and the environment. Researchers have now developed a new machine learning tool to assist in quickly and easily predicting the ferromagnetic crystal properties of novel material compositions.”
