There are a lot of different kinds of somatosensory receptors (touch, temperature, proprioception, nociception, introception), and it's hard to tell which receptor would be most suited to transducing a magnetic stimulus, much less if it truly does. I think, to be honest, we can't really know what the heck true magnetoception is until we grow some magnetite crystals in our noses.
