(a) Image obtained with a microscope of the micro-needle distribution in Ferrocell for a magnetic field perpendicular to the plane of the plate together with the diagram for the Airy pattern obtained by diffracting a 532 nm green laser. With this apparatus, we can measure the diameter of micro-needles. (b) Theoretical and experimental Airy patterns obtained with Ferrocell with an external magnetic field of 400 G and with a field of 600 G. The average diameter d of the micro-needles is around 4.3 μm. In (c), we have the intensity graph and these plots were obtained transforming the images in grayscale.
