A fluorocarbon-based ferrofluid, with about 400-G saturation magnetization and low field magnetic susceptibility of 3, is placed within a glass Hele-Shaw cell of 1.1-mm gap. Magnetic fields are applied that have in-plane clockwise rotating and dc axial magnetic fields. The ferrofluid is surrounded by a 50/50 mixture of isopropyl alcohol and deionized water, which prevents ferrofluid wetting of the glass plates. In all cases, the rotational field strength is 20 G rms, and the frequency is 25 Hz. The dc magnetic field will be increased from 0 to 100 to 200 G. The first... |
