Error quantification: Boosted loop advection. Error of the out-of-plane magnetic field component \(B^{z}\) (left) and divergence of B (right). For this test, we chose \(\boldsymbol{v}=0.5\sqrt{0.5} (1,1,0)\) and \(\beta=\sqrt{0.5} (1,0,0)\), resulting in an advection in the direction of the upper-left diagonal.
