I read the limits of typical ferrite cores and it seems that most sources claim that they tend to work somewhere up to 1 Mhz. Surely they work great under that frequency, but is there any material that could provide a core material for a wide frequency range starting from few tens of Khz up to tens if not hundreds of Mhz?
The problem is I need a high strength B field at high frequency, and making a coil with air as the core material then demands extreme kA currents through the coil in order to achieve decent (up to 1T field strengths) I was wondering can this be somehow resolved by adding a core material to increase the permeability a bit so to decrease the required current through the coil itself?
Any ideas folks?
Thanks.
