We provide the quasiclassical derivation of the modified chiral magnetic effect in the case when massless charged fermions moving in external electromagnetic fields interact by electroweak forces with the background matter. In our study we rely on the energy balance between the external electromagnetic field and charged particles. The obtained expression for the electric current along the external magnetic field appears to coincide with our previous results based on the purely quantum approach. We also compare our results with findings of other authors.
