"electric motors lose energy due to friction when flipping magnetic orientation... overcome using metallic glasses lacking crystal lattice with freely reorienting magnetic domains drastically reducing heat generation/ energy waste...  extends battery range, cooler-running motors, eliminates need for critical elements like cobalt... three 70–80% iron alloys highly resistant to crystallization identified, compatible with laser powder bed fusion 3D printing... e-bikes, drones, electric scooters"
