DEVICE FOR MEASURING A B-COMPONENT OF A MAGNETIC FIELD, A MAGNETIC FIELD SENSOR AND AN AMMETER

摘要

The invention relates to a device (10), a magnetic field sensor and an ammeter. According to the invention, a field distribution (50) of a first electrical field is provided in an area (20) whereby causing the magnitude of the x-component of the first electrical field to monotonously increase in the X-direction.
