If that so-called "electromagnetic barrier" are the electric field AND the magnetic field, then I think Mugino does not have it. Remember that for the electric field and magnetic field to coexist, electric charges must move, meaning you need current that steadily flows (refer to Maxwell's equations). So, that so-called "electromagnetic barrier" of Mikoto is the result of current constantly flowing in her body, and only electromasters can do that. Since Mugino does not have current constantly flowing in her body, she can't have that electromagnetic barrier.
