Fast control coil is one of the most important components for EAST device to control the vertical stability of plasma. However, once the heating power of EAST is updated to 36 MW, fast control coil doesn't adapt to the new operation state and couldn't provide effective control for plasma vertical instability. Thus, insulation material with ITER-like magnesium oxide is developed to withstand high radiation and the coil position is also relocated to obtain more effective instability control. Given the relocation of fast control coil, electromagnetic load acting on coil-self and feeders are calculated based on elliptical integral and Ampere force law. The electromagnetic load as volumetric force is interpolated into the finite element analysis model to analyze the stress state on fast control coil. Finally, the design-by-analysis method is adopted to evaluate whether the stress could satisfy the specified acceptance criteria. The study will provide theoretical reference for the update of fast control coil from the perspective of electromagnetic load.
