Reply to comment by ScootysDad in Some animals can generate electricty, and others can supposedly sense the Earth's magnetic field, but is any animal known to generate a magnetic field of its own? by Redditor_From_Italy
That's true, but also meaningless. Any atom has moving electrons in it (except some H^+ and He^+2, if we're being pedantic). So under your definition literally everything produces a magnetic field.
The magnetic field from a few molecules however, is negligible, and only when compounded by aligning together many such fields do you get anything substantial enough to mean anything.
Tying this back to the original question, OP is clearly talking about macroscopic fields, as considered in biology, and not infinitesimal fields like those produced by a single hemoglobin molecule

Like I said the magnetic fields are there we just can't make use of it yet. In the future machines that can exquisitely tease out those details can have major influence in diagnostics and security.
