Abstract
The quantitative relations and limitations when compensating false sig nals in a ferromagnetic pickup transducer for measuring the magnetic f ield gradient using compensation cores made of permalloy are considere d. It is shown that for a length of the compensation cores equal to th e length of the main cores of the ferromagnetic pickup, one can compen sate the inequality in the conversion factors of the semi-elements up to 3% and the nonparallelism of the axes of the semielements up to 0.8 angular degrees.
