Transient eddy current in magnet structure members
A computer program was developed to model transient eddy current in thin, connected plates. Eddy current is deduced from the solution of an equivalent-network problem. Loop currents are introduced by a transformation as the unknown variables of the network equations (Kirchoff's laws). The network equations are solved numerically by the Runge-Kutta method. This program is quite efficient, allows for holes and multiple materials, and has built-in rotational symmetry options. For cases with known solutions, the model has been checked for both spatial and temporal profiles of the eddy current. Results are given for eddy current profile and eddy current loss in the magnet case, support plate, and several other magnet structure members.
