Cloaking a three-dimensional object in free space from electromagnetic waves has recently become a theoretical possibility, although practical implementations can only be made in reduced Smoothie cup straw schemes.If static fields are involved, requirements are less restrictive and some practical realizations have been possible.Here we present a third regime between the full wave and the static cases.We experimentally demonstrate that a cloak constructed under the dc conditions can keep cloaking properties for applied magnetic fields oscillating at low frequencies (up to hundreds Knitwear of Hz).

Because electromagnetic technology works at these frequencies, applications of our ideas to present technology are discussed.
