There are bacteria that can sense magnetic fields and sharks can sense electric fields. These are real sixth and seventh senses. But humans don't have them.
I have read discussion through the years of evidence of human magnetic field detection; see http://www.ncbi.nlm.nih.gov/pubmed/17069982 for an example abstract.
Humans (some?) can also detect polarization, which I would consider a separate sense from plain vision (see Haidinger's Brush).
