In the presence of the fluid helicity v · ω , the magnetic field induces an electric current of the form j = C HME ( v · ω ) B . This is the helical magnetic effect (HME). We show that for massless Dirac fermions with charge e = 1 , the transport coefficient C HME is fixed by the chiral anomaly coefficient C = 1 / ( 2 π 2 ) as C HME = C / 2 independently of interactions. We show the conjecture that the coefficient of the magnetovorticity coupling for the local vector charge, n = C B ω B · ω , is related to the chiral anomaly coefficient as C B ω = C / 2 . We also discuss the condition for the emergence of the helical plasma instability that originates from the HME.
