The noise, produced by different ferrofluidic samples under their probing by optical fiber method, investigated. It is shown that the magnetic field switching on leads to its significant enhancement, which presumably connected with fluctuations, accompanying the process of aggregates formation. The dependencies of root mean square value of the noise on the field strength and the probing light intensity are obtained. The slow decrease of the noise root mean square value after the field switching off, reflecting the field formatted aggregates relaxation, revealed.
