force is generated by the coupling of the induction current and the magnetic field in the melt. As a result, the energy density of the magnetic field represents pressure acting orthogonally on the magnetic field and towards the centre of the melt[8], so the resulting pressure difference imposed on the melt causes vigorous agitation as soon as the action of the electromagnetic force is felt. Fig.4......
