Here, we compute the low-bias current density, and through the Biot-Savart law calculate the resulting magnetic field of cyclic and linear molecules where strong ballistic ring currents appear. We establish design rules for achieving substantial magnetic fields in single-molecule junctions, and finally discuss potential applications along with the limitations of our study. no imaginary frequencies. Using these structures, we created single-molecule junctions with s-band electrodes. The electrodes consist of two dihydrogen molecules, and the amineterminated molecule is placed between them with an N-H distance of 1.5 Å, a C-N-H bond angle of 110 • .
