Intrinsic anomalous Hall effect (AHE) formulated by geometric properties of Bloch wave functions is a ubiquitous transport phenomenon not limited to magnetic systems but also allowed in nonmagnetic ones under an external field breaking time-reversal symmetry. On the other hand, detection of field-induced AHE is practically challenging because the band modulation through the Zeeman and spin-orbit couplings is typically small compared to other contributions as induced by the Lorentz force. Here, we demonstrate on Dirac semimetal ${\mathrm{Cd}}_3{\mathrm{As}}_2$ films that the field-induced AHE in nonmagnetic systems can be quantitatively probed by applying and rotating the magnetic field within the Hall deflection plane. Measurements on the ${\mathrm{Cd}}_3{\mathrm{As}}_2$ (112) plane reveal that AHE emerges as a clear threefold symmetric component for the in-plane field rotation. This intrinsic response becomes more pronounced in ultralow-electron-density films where significant variations in the geometric properties are expected under the magnetic field. Our findings open new opportunities in the research of Hall responses manifested as orbital magnetization in nonmagnetic systems.
