According to Faraday's law, time-varying magnetic fields induce corresponding electric fields, affecting ions and dipoles. However, the symmetrical patterns of sinusoidal and square magnetic fields often limit their effectiveness. This study proposes the use of sawtooth magnetic fields (STMFs) for their ability to generate asymmetrical electric fields. STMFs create strong electric fields in one direction over a short duration and weaker fields in the opposite direction over a longer period, potentially improving effectiveness. Supporting evidence includes studies on transcranial magnetic stimulation, showing the superior impact of monophasic pulses compared with biphasic ones. Furthermore, research on pulsed and switching magnetic fields has demonstrated significant impacts on brain signals, cognitive function, drug delivery, and oncology applications. If validated, STMFs could advance therapeutic interventions and biomedical research.</p>","PeriodicalId":29923,"journal":{"name":"Bioelectricity","volume":"7 2","pages":"134-138"},"PeriodicalIF":1.5,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12178726/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144477031","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
