The core of the EIC physics program\u0000is the 3D imaging of partonic structures in protons and nuclei. The\u0000experimental detector setup required to enable this primary objective utilizes\u0000\"far-forward\" (FF) and \"far-backward\" (FB) detectors positioned downstream in\u0000the hadron-going and electron-going directions, respectively, from the\u0000interaction point of the EIC. The primary purpose of the FB detectors is to\u0000monitor luminosity and measure scattered electrons in collisions in the EIC,\u0000while the array of FF detectors is used to tag and reconstruct both charged and\u0000neutral particles that scatter at small angles. These detectors also enable a\u0000broader physics program than was initially envisioned, enhancing the EIC's\u0000research potential. The expanded capabilities have been a prime focus for\u0000engaging the broader nuclear physics community to build a robust groundwork for\u0000the EIC.

One of the key\u0000components is a large acceptance dipole magnet with a central field of 0.5 T\u0000and the homogeneity of 5% within a 1 m long, 1.2 m wide, and 0.9 m high\u0000aperture.

The magnet is designed as a coil-dominant type, with\u0000conductors discretized on a racetrack-shaped cross-section to generate the\u0000necessary fields. A warm iron yoke is used to enhance the central field and\u0000minimize the stray field. The magnet has overall dimensions of 3.4 meters in\u0000length, 2.7 meters in height, and 4.3 meters in width.
