This paper presents an investigation on ac losses of superconducting bulk caused by various magnetic wave conditions with the help of finite element software of Comsol Multiphysics. Three different magnetic wave conditions are analyzed, which are standing magnetic field, rotated magnetic field and traveling magnetic field. The calculation ac loss result was compared with that from analytical formulas for type-II superconducting slab and cylinder. The influences of the strength of external magnetic field on the ac losses were investigated. Effects of a relatively stable trapped-field of superconducting bulk on ac losses in time-varying magnetic field are clarified. Effect of spatially inhomogeneous distribution of the external magnetic field on the ac loss is studied.
