There are results of the magnet system numerical computation of the Anode Layer Thruster with power up to 100 watts, taking into account heat generation while its work. The description of the numerical model for computation of thermal condition of the thruster is given and the results of the computation are shown. On the basis of the obtained profiles of temperature distribution depending on the amount of heat the computation of the magnetic system is made. The range of powers at which there is no significant demagnetization of the magnetic elements of the system and disturbance of the magnetic field profile in the channel of the thruster. Numerical computations were carried out in the software package ANSYS.

Key words: thruster with anode layer, thermal state, the magnetic system, demagnetization.
