A novel approach to the transient analysis of a magnetic field is presented that uses the formulation of a boundary-element model in two-dimensional problems. In order to solve the transient problems, state equations are formed using the boundary element model, and are solved using the variable transformation based on eigenvalues. The computational accuracy of the proposed method is evaluated by an infinite plate model and an infinite cylinder model in which the impressed magnetic flux densities are given by a unit step function and a sinusoidal function respectively
