Influence of magnetic field gradients on the test body of the absolute ballistic gravimeter ABGVNIIM-1 is considered. Based on the protocol for measuring the magnetic field in the working region and data on magnetic fields of the pump magnetic system of the gravimeter, gradient models are created. Using the finite elements method, deviation of measured value of free fall acceleration from the initial one is calculated. Recommendations for design of the test body and the whole instrument are formulated.
