• We theoretically study the equilibrium axial current jeq5, which is the difference between the charge current of left-handed and right-handed helicity of the Weyl fermions, in the junction of a magnetic insulator attached to Weyl semimetals with time-reversal breaking and inversion symmetry. The charge current of each helicity jeqγ=± is induced by the localized spin S of the magnetic insulator. jeqγ=± is proportional to ∇ × S and is independent of the sign of γ. As a result, the difference between jeqγ=+ and jeqγ=− are canceled out, and jeq5 is zero.
