H₂generation performance and ROS scavenging ability of Mg rods under AMFs. (a) Schematic diagram showing the eddy-thermal effect of Mg implants under an AMF. (b–d) The temperature increase resulting from the eddy-thermal effect depended on the length (b), and diameter (c) of the Mg rods under different AMF intensities (d). (e) Photograph showing the H₂ generation in PBS from Mg with or without AMFs. (f) UV–vis absorption spectra of the MB solution containing Mg rods with an AMF after different times. (g) MB reduction properties of Mg rods with or without an AMF at different time. (h) H₂ generation performance of Mg rods in PBS at different temperatures. (i) Cumulative release of Mg²⁺ from Mg rods in PBS at different temperatures. (j) UV–vis absorption spectra of TMB after incubation with Fenton agents and Mg rods with an AMF after different times. (k) Comparison of •OH scavenging ability of Mg rods with or without an AMF at different time. (l) ESR spectra showing the •OH scavenging ability of Mg rods with or without an AMF. (m) UV–vis absorption spectra of •ABTS⁺ radical after incubation of Mg rods with an AMF after different durations. (n) Comparison of the •ABTS⁺ scavenging ability of Mg rods with or without an AMF at different time. (o&p) SEM images of Mg rods before (o) or after (p) being placed in an AMF. n = 3 independent samples. P values were calculated by the two-tailed student's t-test. **p < 0.01, and ****p < 0.0001.
