In this work we show that radiation can have interesting effects on a superconducting inductive circuit. Consider that for some time a battery supplies a constant voltage to a ring made of a superconductor wire above its critical temperature. At some instant the battery is disconnected and the ring is immersed in a low temperature bath, its resistance becoming zero. We study the system right after it undergoes the phase transition and enters the superconducting state. The system is modeled as an ideal selfinductance, and the radiation emitted is modeled as magnetic dipole radiation. We analyze qualitatively the differential equation that models the electrical current evolution to obtain some of its main characteristics. We find that, depending upon its initial conditions when it enters the superconducting state, the electrical current can evolve in one out of three very well differentiated sets of states. The first set consists of just one state where the current decays exponentially, in a similar fashion as it would do if the phase transition would have not taken place. The second set is comprised of short-lived states, where the current decays faster than the exponential state, and dies suddenly. The third set is comprised of long-lived states, where the current decays slower than the exponential state and reaches smoothly a constant value different from zero at a finite time. It stays in that state and actually lives in it forever.
