We attempt to predict the consequences of adding an inductive current transformer (OH Transformer) to the present S-l Spherornak experiment. Axisymmetric modeling with only classical dissipation shows an increase of toroidal current and a shrinking and hollowing of the current channel, conserving toroidal flux. These unstable profiles will undergo helical reconnection, conserving helicity K = JA-B dr while increasing the toroidal flux and decreasing the poloidal flux so that the plasma relaxes
