Tiny magnetic “flowers” engineered by physicist Anna Palau are redefining how we manipulate magnetic fields. These metamaterials, designed with petal-like structures, focus magnetic energy to a central point, amplifying it dramatically. Tested at BESSY II using a cobalt rod, they demonstrated the potential to supercharge magnetic sensors and imaging tools. This leap in field concentration [...]from SciTechDaily https://ift.tt/h79bOqe
