According to Biot-Savart law, the magnetic induction at the diameter position of the spin axis is calculated. Furthermore, using the internal and external radius of the Earth's outer core as well as the radius of the Earth and the magnetic induction at the Earth's magnetic pole, the volume charge density and surface charge density of the Earth's outer core have been obtained.

The result shows: the maximum of the exchange bias field moves towardsthe easy axis with increasing the biquadratic coupling field or bilinear coupling field;additionally, the oscillations of the curves for the angular dependence of exchangebias field become weak and gradually resembles the sine function with increasing thebiquadratic coupling field.
