Resumen
- Benchmark problem 5 of the TEAM workshops consists of four aluminium blocks placed in the space between the jaws of an electromagnet. Three dimensional eddy currents are induced by 50 Hz time‐varying flux. Eleven sets of results from nine groups of contributors are compared with experimental measurements. The results from most of the computer codes tend to converge to common limits. These limits are in some places slightly different from some of the measured results. The reason for this discrepancy is thought to be due to the idealised boundary conditions, ignoring any losses in laminated iron, which are assumed in all the computer models.
