Magnetic diverters are commonly used in order to reduce the AC loss in superconducting coils. However, they have not been proved to work on YBa(2)Cu(3)O(7-x)-coated conductor coils. Moreover, modeling tools are required for predicting the resulting AC loss and understanding the loss mechanisms. In this paper, a coated conductor pancake coil with ferromagnetic diverter is measured and simulated. The magnetic diverter reduces the AC loss but the critical current practically does not change. Our simulations show that a diverter wider than that in the measurements can reduce the loss below that of a single strip. Therefore, the optimum diverter size should be obtained by simulations.
