Abstract: We present an isolated analytical model for the ohmic heating in the interior of hot jupiters, treating
the wind zone as a parameterized boundary condition. Under a conserved estimation of the strength
of induced field and the assumption of an isothermal-convective planet model, we conclude that the
mechanism of ohmic heating may not explain the over-inflated radius of hot jupiters along. We also
develop a new time dependent evolution model for hot jupiters with ohmic heating, further show
that ohmic heating is important only when the planet mass is small or the planet is at late stage of
evolution.
