The velocity of the positron $\vec v_+$ points in the $\hat y$ direction while $\vec r \propto \hat x$, so their cross product (the $\vec B$ field) is in the $\hat z$ direction. The cross product of $\vec v_x \propto \hat x$ with this (the Lorentz force due to the magnetic field) is therefore in the $\hat y$ direction. | |
