N2 - Melting widely exists in various industrial applications and melting control through an extra magnetic field is a promising subject. Recent studies mainly focus on the suppression effect of the magnetic induced Lorentz force. However, the influence of magnetic force is less investigated. The present study concentrates on investigating the impact of magnetic force, along with gravity, on the melting process. The magnetic quadrupole field is used to generate magnetic force and the temperature distribution, velocity field and melting front are obtained through lattice Boltzmann method. Results indicate that the magnetic force can enhance the flow and heat transfer during the melting process and it has the potential to be used to control the process. Besides, the gravity accelerates the melting process when the dimensionless magnetic force parameter is less than 20, whereas its effect can be ignored when the parameter is larger than 20.
