Magnetic evolution profiles with 13 TW of the heat flow across the CMB at present. The heat flow across the CMB is assumed as: \( {Q}_{\mathrm{CMB}}={Q}_{\mathrm{CMB},p}\exp \left(\frac{f\left({t}_a-t\right)}{t_a}\right) \) where QCMB, p is the present-day heat flow across the CMB, f = ln(QCMB, 0/QCMB, p)/ta, QCMB, 0 is the initial value of the heat flow across the CMB, which is 25 TW, and ta is the age of the Earth (4.6 billion years)
