In this paper, we investigate the transient response of Lorentz force at finite magnetic Reynolds numbers Rm on an electrically conducting rectangular bar that is strongly accelerated in the presence of a localized magnetic field. This is done through numerical simulations utilizing a coupled finite-difference boundary element approach. The results show good qualitative agreement with existing experiments with a circular cylinder. The Lorentz force rise time is seen to be a linear function of Rm. The linear dependence of Lorentz force on Rm is found to be valid only for low values of Rm, after which the slope decays leading to an apparent saturation in the Lorentz force at sufficiently large values of Rm. Our results provide important information for the development of Lorentz force flow meters for transient flow applications. Index Terms: Lorentz force velocimetry (LFV), magnetic Reynolds number, transient response.
