It's a copper band wound around the outside of the core and windings. It acts as a shorted turn to leakage flux, helping to contain it.

On a power transformer it can help lower radiated noise (like diode recovery spikes) from getting into other curcuits.

Mark Knopfler wore a luminous one tied over his brow for the "Money for nothing" video.
