Magnetic ferrofluids, although they are made of tiny ferromagnetic particles suspended in liquid, are sometimes considered paramagnetic since they cannot be magnetized.

Magnetic field lines, represented as arrows, are excluded from a superconductor when it is below its critical temperature.

Magnetic moment displacement is ostensibly the main disturbance, yet submarines are detectable even when oriented parallel to the Earth's magnetic field, despite construction with non-ferromagnetic hulls.

Magnetic gradiometers are pairs of magnetometers with their sensors separated, usually horizontally, by a fixed distance.

Magnetic materials in the sensor itself are the primary cause of this error.
