Zusammenfassung:Embodiments disclosed herein generally relate to a magnetic write head. The magnetic write head includes a write pole, a shield and a first coil disposed around the write pole. The magnetic write head further includes a magnetic circuit and the magnetic circuit includes a loop of magnetic material and a second coil disposed around the loop of magnetic material. The magnetic circuit magnetically resets the shield to improve far track interference.
