   The paper deals with experimental detection of tiny magnetic particles deposited in oil. An iron powder magnetized using stationary magnetic field simulates the magnetic particles. The powder is sprinkled in oil and a fluxgate magnetometer is utilized to measure its remanent magnetic field. Several variables are altered during the experiments and their influences on the measured data are summarized. It is revealed, that even the measured values of the magnetic field intensity are in order of units of Am^-1, the fluxgate sensors are sufficiently sensitive to detect such weak magnetic field.
