The localized region of electric and magnetic tangent loss is controlled and modified in induced high magneto-optical atomic medium. Significant electric and magnetic tangent losses is investigated under parity time symmetry condition [Tanδe,m(x,y)]=[Tanδe,m(−x,−y)]∗. Single and four localized peaks of electric and magnetic tangent losses is reported, which shifted from quadrant to quadrant with coordinates inversion. The maximum electric tangent loss is measured to 1.5 dB/m and magnetic tangent loss is measured to 1 dB/m. The modified results of this manuscript is useful for magnetic resonance imaging and radar absorbing materials. •The paper investigates localized electric and magnetic tangent losses in a high magneto- optical atomic medium.•The density matrix formalism is used to derive polarization and magnetization from coherence terms, connecting permittivity and permeability with tangent losses.•Tangent losses are analyzed under parity-time symmetry, showing that [Tanδe,m(x,y)]=[Tanδe,m(−x,−y)]∗•The study identifies single and four localized peaks of tangent losses, shifting across quadrants with coordinate inversion.•The maximum electric tangent loss is 1.5 dB/m, and the magnetic tangent loss is 1 dB/m.•Results are significant for applications in magnetic resonance imaging (MRI) and radar-absorbing materials.
