Magnetic fields measuring method for energy self-efficient information transmission in motor vehicle, involves bridging voltage drop resulting from external magnetic field to characteristics of external magnetic field

摘要

The method involves charging a magnetic core (1) of a measuring device with a magnetic flux. An induction voltage (U2) is generated by using a consumer coil (3). A voltage drop is detected along the coil. The coil is attached to the core such that an inductance of the coil is dependent on magnetic resistance of the core. The measuring device is brought into an external magnetic field (5). The voltage drop resulting from the external magnetic field is bridged to characteristics of the external magnetic field.
