We have formulated the coupled equations of mo- tion for the electroweak MSSM with a Lagrangian that adds the right-handed Stop field terms to the Standard Model. 

In this model a first order EWPT can occur with satisfactory baryogenesis. By using an I-spin ansatz for spherically symmetric bubble nucleation we were able to derive a Maxwell-like equation of motion for

the electromagnetic field with the current given by the electrically charged gauge fields, W $^{±}$, as well as the charged fermion currents. Moreover, by treating the W$_{t}$ and W$_{j}$ components separately we were able to decouple the equations for the W ± fields from the other gauge fields, and also the Higgs and Stop fields, and obtain the current for the electromagnetic field. 

In the present paper we derived solutions for the electromagnetic field caused by EWPT bubble nu-
