We study the chaotic scattering of charged particles in an open three-disk billiard subject to a uniform magnetic field. We identify qualitatively distinct behaviors depending on the field strength: hyperbolic, pruned, Kolmogorov-Arnold-Moser theorem torus dominated, and regular phases. The hierarchical structure of the chaotic set and the time delay function is investigated. Our main finding is that with increasing field strength the degree of chaoticity decreases while the complexity of the small scale structures may increase. Possible consequences of our results for the ballistic transport in microjunctions are discussed.
