Currently, one of the major challenges in the automotive industry is the development of direct current (DC) electrical motors. A DC vehicle motor incorporates strong magnetic fields at the rotor location. The higher the magnetic field in a reduced volume, the better the engine efficiency factor. A research team based at JEOL France recently studied the composition of such a magnet using a FIB-SEM technique coupled with a specialized analysis software package.
