The utility model discloses a combined magnetic core with different magnetic conductivities. The combined magnetic core comprises a magnetic core upper yoke, a core column magnetic core body and a magnetic core lower yoke. The magnetic conductivity of the magnetic core upper yoke and the magnetic conductivity of the magnetic core lower yoke are not equal to the magnetic conductivity of the core column magnetic core. The core column magnetic core is located between the magnetic core upper yoke and the magnetic core lower yoke. The top end of the core column magnetic core body makes contact with the magnetic core upper yoke, and the bottom end of the core column magnetic core makes contact with the magnetic core lower yoke. The magnetic core upper yoke, the core column magnetic core body and the magnetic core lower yoke form a closed magnetic circuit. As the combination of magnetic core bodies with the different magnetic conductivities is adopted for the magnetic core upper and lower yokes and the core column m
