In this paper, we present the preliminary results of a local magnetic field measurement at the position of 40Ca+ ion. We employ the simultaneous locking of the frequency of clock laser onto two transitions of Zeeman sublevels on transition 4s 2S1/2 (m=-1/2) - 3d 2D5/2 (m=-1/2 and -5/2). The frequency deviation from the spectral line center of both selected Zeeman transitions determines the magnetic field value on basis of the linear Zeeman shift thus one can estimate the clock frequency of the unperturbed 4s 2S1/2 - 3d 2D5/2 transition.
