In relativistic magnetized plasmas, asymmetry in the number densities of
left- and right-handed fermions, i.e., a non-zero chiral chemical potential
mu_5, leads to an electric current along the magnetic field. This causes a
chiral dynamo instability for a uniform mu_5, but our simulations reveal
dynamos even for fluctuating mu_5 with zero mean. This generates small-scale
magnetic helicity and turbulence. A large-scale mu_5 emerges due to chirality
conservation. These effects amplify a mean magnetic field via the magnetic
alpha effect and produce a universal scale-invariant mu_5 spectrum.
