To shield Mars from the same amount of cosmic radiation as the Earth, we want Mars' magnetopause to be approximately 20 Mars radii away from its center: about the same distance from Earth's center to its magnetopause.  $R_{Magnetopause}=(\frac{2B_0^2}{\mu_0\rho_{sw}v_{sw}^2})^{1/6}$ $R_{Magnetopause}=\frac({2B_0^2}{\mu_0\rho_{sw}v_{sw}^2})^{1/6}$  where $B_0$ is the magnetic dipole moment of the planet and $\rho_{sw}$ and $v_{sw}$ are the density and velocity of solar wind at Mars' orbit respectively.
