                      Jülich GmbH, IEK-4, 52425 Jülich, GermanyCurrently, the
                      most advanced concepts for fusion confinement are the
                      tokamak and the stellarator. The former is toroidally
                      symmetric and 2D; the latter is a 3D device with a smaller
                      degree of symmetry. The tokamak scheme is currently a
                      leading variant for plasma confinement and is therefore
                      being used for the ITER design and is planned for the DEMO
                      reactor. It has recently been realized that 3D magnetic
                      topology effects also play a significant role in this 2D
                      concept. The results obtained from various tokamaks have
                      shown that magnetic field perturbations can either
                      completely suppress edge localized modes (ELMs), trigger
                      small ELMs during ELM free periods, or affect the frequency
                      and size of the type- ELMs in a controllable way, preserving
                      good global energy confinement [1,2]. Although the physic s
                      mechanism is still unclear, experimental results from those
                      different devices demonstrate that the magnetic topology
                      plays a key role in plasma confinement [3], edge MHD
                      stability [4], and interactions between the plasma and the
                      first wall, particularly with the divertor [5-7]. Recently,
                      3D magnetic topology effects form one of the hottest topics
                      in fusion research today, and understanding them is
                      essential for the success of future fusion devices. In this
                      paper, an overview of physics understanding of various 3D
                      effects on major MHD activities, i.e. tearing modes and edge
                      - localized modes, [5-7], and plasma edge [8] and divertor
                      transports [9-11] in magnetically confined plasmas will be
                      presented . In addition, comparing the advantages and
                      disadvantages of 2D and 3D magnetic topology effects in
                      magnetic confinement fusion will be discussed.},
