Magnetization reversal dynamics of NiFe nanofilm elements were studied with micromagnetic simulation. Magnetization reversal and spin-wave dynamic properties are effectively tuned by tailoring end shape of NiFe nanofilm elements. As magnetization reversal occurs,it is accompanied by a soft magnetic mode whose spacial symmetry determines initial steps(onset) of microscopic magnetization phase transitions path. There exists a critical tapered parameter h 0 . For elements with tapering parameter h
