Magnetic moment of the $\Delta^{++}$ baryon is computed within the new approach based on the QCD string Hamiltonian. The string tension $\sigma$ is only dimensionful quantity forming magnetic moments of both nucleon and $\Delta$, but color Coulomb and spin-spin interactions cancel each other in the nucleon case while in $\Delta$ they add coherently. The result $\mu_{\Delta} = 4.36\mu_N$ is in good agreement with experimental data.
