This angle is recognized as the "pitch angle" in the particle. The distance, or radius, of the electron from the field line Anytime is referred to as its Larmor radius. The pitch angle will increase since the electron travels to some region of bigger industry power nearer into the environment. Hence, it is feasible for some particles to return, or mirror, In the event the angle results in being 90° right before getting into the ambiance to collide Together with the denser molecules there.
