on the layer composition. This phenomenon can be attributed to the role of thermo-electromagnetic convection and Lorentz force on the Cu dissolution as well as the accumulation of Cu solute at the interface front. Key words: magnetic field; SnZn alloy; intermetallic compound; Cu dissolution 1 Introduction The recent development of superconducting magnetic techniques has provided a rather large opportunity......
