High spin states in ${}^{103}\mathrm{Ag}$ were investigated with the Gammasphere array by using the ${}^{72}\mathrm{Ge}$(${}^{35}\mathrm{Cl}$,$2p2n$)${}^{103}\mathrm{Ag}$ reaction at an incident beam energy of 135 MeV. A $\Delta J=1$ sequence with predominantly magnetic transitions and two nearly degenerate $\Delta J=1$ doublet bands have been observed. The dipole band shows a decreasing trend in the $B(M1)$ strength as function of spin, a well-established feature of magnetic bands. The nearly degenerate band structures satisfy the three experimental signatures of chirality in the nuclei; however, microscopic calculations are indicative of a magnetic phenomena.
