    "abstract": "We consider the induction of magnetic field in flows of electrically\nconducting fluid at low magnetic Prandtl number and large kinetic Reynolds\nnumber. Using the separation between the magnetic and kinetic diffusive\nlengthscales, we propose a new numerical approach. The coupled magnetic and\nfluid equations are solved using a mixed scheme, where the magnetic field\nfluctuations are fully resolved and the velocity fluctuations at small scale\nare modelled using a Large Eddy Simulation (LES) scheme. We study the response\nof a forced Taylor-Green flow to an externally applied field: tology of the\nmean induction and time fluctuations at fixed locations. The results are in\nremarkable agreement with existing experimental data; a global $1/f$ behavior\nat long times is also evidenced.",
