In this poster, finite element based electromagnetic analysis work carried out for the two Indian tokamaks SST-1 and ADITYA is summarised. As a part of Indian Fusion Pogramme, first Indian tokamak Aditya and first Indian steady superconducting tokamak SST-1 are constructed & being operated at Institute for Plasma Research. These experimental toroidal fusion devices contain several magnetic field coils (TF, PF & central solenoid etc.) to produce, confine and control plasma at high temperature. Using Comsol Multiphysics AC/DC Module, a detail electromagnetic simulations have been carried out to calculate 3-D magnetic field profiles, error fields due to coil misalignments, eddy currents generated due to transient fields, transient electromagnetic forces & stresses on varoius coils and magnetic null correction requirements.
