The inventors have developed technology to facilitate the inspection of vehicles, such as cars, to determine one or more characteristics of the vehicles. The characteristics of the vehicles may be determined based on magnetic field signals recorded from the vehicle, during the operation of the vehicle. The technology includes hardware, software, and trained machine learning models for performing analyses to determine vehicle characteristics. The vehicle characteristics may include a make, model, drivetrain, battery type, electronic component condition, and/or vehicle structural condition. The vehicle conditions may be used in the generation of a vehicle report for later analysis.

Magnetic core assemblies include a skewing feature that introduces transverse components into the power flux density vector are disclosed herein. A magnetic core assembly comprises a lower core having a center section and an upper core having a center section. The center sections are aligned to form a center post. A power winding that receives current is wrapped around the center post. The core assembly further comprises a power flux density vector that has transverse and non-transverse components. The transverse components have a higher magnetic reluctance than the non-transverse components. When the assembly is used with a transverse winding, the transverse components from the magnetic core assembly produce a transverse voltage waveform on the transverse winding. The transverse voltage waveform may be observed to detect a change in the sign of the slope of the transverse voltage waveform. The change in the sign of the slope indicates magnetic saturation.
