The dependence of the free energy, order parameter and susceptibility on the field for Ising-like magnet in the case $T=T_c$, where $T_c$ -- phase transition temperature absent the field, is calculated. The critical exponents and critical amplitudes of these values are founded. The dependence of the critical amplitudes on the microscopic parameters of the system is established.
