Electric car

Belongs to:
Electric vehicles
Description:

Electric cars are vehicles that are driven by an electric motor and obtain the necessary energy from an accumulator. For a complete charge, charging time may reach up to 8 h. Electric vehicles do not emit any noxious fumes. They can reach a range of approx. 200 km. Electric cars can generate very high magnetic fields due to large battery currents and the electric motor, especially during starting and stopping.

Frequency ranges:
  • 2 Hz–3 kHz
Type of field:
magnetic
