AB  - Electromagnetic fields produced in relativistic heavy-ion collisions depend sensitively on the initial spatial distribution of nuclear charge. Using the Liénard--Wiechert potential with a triaxially deformed Woods--Saxon density, we calculate the transverse electric and magnetic field distributions in ^129Xe+^129Xe collisions at √(s_NN)=5.44 TeV. We systematically examine how the triaxiality angle γ modifies the field structure at the collision time (t=0) in semi-central events, using spherical nuclear collisions as a baseline. The results show that nuclear triaxiality causes distinct spatial redistributions of both electric and magnetic fields in the transverse plane. These findings indicate that initial electromagnetic fields encode key information on intrinsic nuclear shapes, offering an additional constraint on nuclear deformation and its consequences for field-sensitive observables in heavy-ion collisions.
