A symmetric coupling of methods of finite and boundary elements for numerical solution of
transient eddy current problems is described. This is an essential step in modelling of
electromagnetic forming of metalic sheets. The finite element method is employed in the
conducting region of the metalic sheet. The boundary element method relies on the Stratton-
Chu representation formula and it models the electromagnetic field in the air including its
decay at infinity. We impose external currents by the Biot-Savart law.
