Abstract
A method for compensating in a space volume for a magnetic noise field outside the space volume includes determining a strength of the magnetic noise field outside the space volume; defining a correlation between the noise field outside the space volume and a corresponding noise field inside the space volume, or calculating the noise field inside the space volume on the basis of the measurements of the magnetic field outside the space volume; based on the noise field inside the space volume, generating a magnetic compensation field for neutralizing the noise field inside the space volume; wherein the compensation of the magnetic noise field outside the space volume is carried out along a direction in the space volume which is variable by determining a noise field component inside the space volume along the direction and generating a compensation field of the noise field component along the direction.
