Abstract

A core body for coil or transformer, comprising a core consisting of two core parts of ferromagnetic material that are fixed together so as to define a gap between two surfaces of the core parts, said core being attached to a member non-magnetic having a temperature coefficient different from the coefficient of the core material, the member of which is arranged so that the resulting different expansion coefficients produce a variation in the gap length and adjust the reluctance of the core as a function of temperature, characterized by that the non-magnetic member consists of a thin metal plate (6) that is kept in close contact with a surface of the core (1 and 2).
