Description

TECHNICAL FIELD The disclosure relates generally to monitoring magnetic fields. In particular aspects, the disclosure relates to reporting magnetic fields of an area to other vehicles. The disclosure can be applied in heavy-duty vehicles, such as trucks, buses, and construction equipment. Although the disclosure may be described with respect to a particular vehicle, the disclosure is not restricted to any particular vehicle. BACKGROUND Modern vehicles, such as cars or trucks, are commonly equipped with sensors and components on which strong magnetic fields have negative effects. For instance, these sensors are utilized to measure speed, position, pressure, temperature, etc., which measured values are supplied to control systems that are needed for propulsion and control of the vehicle. Thus, it is important that a vehicle equipped with these sensors is aware of strong magnetic fields surrounding the vehicle such that the sensors e.g., may be bypassed or inactivated. SUMMARY According to a first aspect of the disclosure, a computer system is provided comprising a processor device configured to monitor, by acquiring at least one measured magnetic field value from a magnetic-field sensing device of a vehicle, a surrounding magnetic field of the vehicle, record a position at which the magnetic field was monitored, the position being acquired from a position-sensing device of the vehicle and to provide an indication of strength of the magnetic field and said position to other vehicles. The first aspect of the disclosure may seek to resolve an issue of making a measured magnetic field and associated position available to vehicles. A technical benefit may include to enable the vehicles to plan an alternative route in case a strong magnetic field is measured along a specific route. According to a second aspect of the disclosure, a computer-implemented method is provided comprising monitoring, by a processor device of a computer system of a vehicle acquiring at least one measured magnetic field value from a magnetic-field sensing device, a surrounding magnetic field of the vehicle, recording, by the processor device, a position at which the magnetic field was monitored, the position being acquired from a position-sensing device of the vehicle and providing, by the processor device, an indication of strength of the magnetic field and said position to other vehicles. In some examples, the providing of the indication of a strength of the magnetic field and said position comprises providing the indication of a strength of the magnetic field and said position to a remotely located device to which the other vehicles have access. A technical benefit may include that the other vehicles may turn to the remotely located device, being for instance a cloud server, at any appropriate time for an indication of the measured magnetic field and position. In some examples, the providing of the indication of a strength of the magnetic field and said position comprises providing the indication of a strength of the magnetic field and said position directly to the other vehicles. A technical benefit may include that the indication of the measured magnetic field and position may be sent directly to a designated vehicle. In some examples, the processor device determines whether the at least one measured magnetic field value exceeds at least one magnetic field threshold value and if so, provides the indication of a strength of the magnetic field and said position to other vehicles. A technical benefit may include that only magnetic fields that are considered strong are reported. In some examples, the recording of the position is only performed if the at least one measured magnetic field value exceeds at least one magnetic field threshold value. A technical benefit may include that the processing unit is not burdened with recording positions unless strong magnetic fields are monitored. In some examples, the providing of the indication of a strength of the magnetic field is performed by providing the at least one measured magnetic field value. A technical benefit may include that other vehicles are given exact measured magnetic field values. In some examples, the providing of the indication of a strength of the magnetic field is performed by providing a categorization of the strength of the magnetic field. A technical benefit may include that other vehicles are given an explicit indication of the strength of the magnetic field, such as “medium”, “strong”, “very strong”, etc., and therefore is not required to perform a determination of the strength. In some examples, the providing of an indication of a strength of the magnetic field and said position to other vehicles is performed via a wireless communication device. A technical benefit may include that data may be swiftly and straightforwardly communicated over great distances at any time. In some examples, the providing of an indication of a strength of the magnetic field and said position t
