Experimental results and comparison with theory (a) Measured density as a function of α defined in (14); triangles are for force driven jumps , circles for torque driven jumps , and the color scale gives the distance between two magnets over their radius at the time of the jump (dcrit/R); the fit yields z = 15 mm. (b) Measured density as a function of β defined in (15); the conventions used are the same as in (a); the fit yields θ = 9∘. (c) Measured density as a function of theoretical density calculated thanks to equation (10); the values used for z and θ are computed from the fits in (a) and (b); the conventions used are the same as in (a).; (d) Comparison between results from method 1 and method 2; data gathered from method 1 are more scattered.
