with alternating orientation however as hereinbefore explained both the position and the orientation of each magnet on one ring may be arbitrarily chosen so to be optimized for a specific application it should be emphasized that there is no physical connection between the inner ring 101 and the outer ring 102 for reasons that will be explain later on in this description based on the laws of magnetostatics the relative position of the inner ring 101 with respect to the outer ring 102 depends on the state of the system u2014 if the system is in a static state or a dynamic state as will be further described in a static state u2014 when the system is at rest each magnet 104 on the outer ring 102 is exactly aligned in front of the corresponding magnet 103 on the inner ring 101 as shown in fig2 in a dynamic state u2014 when one ring is driven into rotation while the other one is connected to a load not completely free to move the relative position of each magnet on the driving ring with respect to the corresponding magnet on the load ring will change and will stabilize to a new state the corresponding magnets 103 and 104 will no longer be perfectly aligned the relative position of the magnets 103 and 104 will shift in a quasi linear fashion tangentially to the circumference of the rings 101 and.
