This is how simulation & testing works for vehicle development
Simulation and simulation-based testing can be effectively used right from the concept investigation stage up to field trials and production consistency assessments.

In the virtual testbed-based calibration of the physical engine, after-treatment and vehicles are replaced by advanced real-time models. Calibrations can be undertaken for engine and vehicle level emissions.
New Delhi: It is no secret that developments for BS-VI emission norms for the Indian automotive industry will require significantly higher calibration efforts as well as development time, due to complex engine and after-treatment controls.
Vehicle developments will have to pass through concept definition, detailing, prototype development and calibrations to meet various parameters such as engine-out emissions, tailpipe emissions with after-treatment, on-board diagnostics, vehicle level performance, off-cycle emissions, including not-to-exceed emissions, real-drive emissions (RDE), or in-service conformity.
In addition, fuel efficiency performance as well as component safety at different ambient conditions and competitive total cost of ownership requirements will also have to be met.
Explanation:
Many materials can work as electromagnet cores, but some common ones are iron, amorphous steel, ferrous ceramics (ceramic compounds that are made with iron oxide), silicon steel and iron-based amorphous tape. In principle, any material with a high relative permeability can be used as an electromagnet core.
