a–c, Measurements were carried out in the HER (a and b) and OER (c) regions for 8 s each. A Pt foil electrode and a Pt mesh electrode were used in a and b, respectively. mag, magnetic field. Linear regression analyses were performed for t > 3 s in a–c. d–f, The slope of the current density decrease over time (dJ/dt, right) and the current density at 8 s (left). The data presented in d correspond to a, panel e shows the data analysis for b and panel f shows the analysed data for c. Data are presented as mean values ± 1 s.d. from 3 independent measurements (n = 3). The corresponding video recordings are available as Supplementary Videos 1–3.
