<p>A magnetic core for a choke or transformer constituted of a closed path ferromagnetic core having six or more gaps formed therein. Preferably, the gaps are selected from air gaps, gaps filled with non-electrically conducting spacers and combinations thereof. Optionally, the magnetic core is constituted of a ferromagnetic material selected from, a ferrite, a soft ferrite, a NiZn Ferrite, a NiCuZn ferrite, a MgZn ferrite, a MnMgZn ferrite, and a ferrite containing as an additive or substituting oxide, at least one oxide selected from oxide(s) of Ti, Cr, Al, Sn, Li, Co, Pb, Bi, V, Si and Ca.</p> |
