    What material should I use in order to have high permeability?
    The material will be set between the primary and the secondary sides of a separable transformer. In other words, the material will create an air gap of 1mm. So I need a material in order to do not lose the fluxes.

    You can buy transformer plates of all sorts of different shapes, so you could fashion whatever you want. This would give you the highest permeability. Ceramics (ferrite) are less permeable but can be cut and even formed. I've seen hobbyists mold their own cores this way. Another trick is to cut coat hanger wire (insulated metal) and bundle the pieces together. Coated nails can be used this way also. The idea is to reduce eddy currents that would be a problem in a solid piece of metal such as a bolt or slab.

    why dont u try new polycrystalline ferrites such as Ni.3Zn.7Fe203 and many others!!!!!
    Can i know what exact application u are using that transformer for( if u wanna share,no compulsions)???
