Chaos in a Magnetic Pendulum Subjected to Tilted Excitation and Parametric Damping

Figure 4

Evolution of the shape of the basin of attraction of the right well as 𝑟 increases for 𝜔=1.5,  𝛾=𝜋/2, and the value of Figure 2. (a) 𝑟=0.05, (b) 𝑟=0.1, (c) 𝑟=0.15, and (d) 𝑟=0.2. The basins have been obtained using a simplified criterion which distinguish solution of mean value of displacement. The marked region corresponds to the region for which the dynamics is attracted in the right well.
