  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.
