“…Asymmetries introduce various changes in the structure of the IDR prevailing under symmetric conditions. Thus, for example, the quadrupolar Hall magnetic field structure becomes dipolar (see, e.g., Mozer, Pritchett, et al, 2008;Muzamil et al, 2014;Pritchett, 2008). The addition of a guide field, that is, a magnetic field component along the direction of the X line, adds complexities to the structure by, for example, giving rise to differences in the Hall B field in the two outflow regions (e.g., Pritchett & Mozer, 2009; see also review by Eastwood et al, 2013).…”
