We’ve known for some time that different people have different sensitivities to static magnetic fields.
There doesn’t appear to be an obvious reason as to who, why or where, but as a health practitioner, you place magnets on enough patients and the differences in sensitivity are obvious.
This video explains a new study that tests if people might be sensitive to changes in the Earth’s magnetic field.
Magnetotropism is how plants and animals respond to magnetic fields, while magnetoreception is the ability of plants or animals to perceive magnetic fields. For instance, magnetic fields have been shown to effect seedling growth and development in a wide range of plants, this is an example of magnetotropism. Whereas birds are able to sense the earth’s magnetic field to help them navigate, an example of magnetoreception.
Novel researchers such as Davis & Rawls gathered quite a following for their beliefs that there are biological differences between the magnetic field at the north and south pole of a magnet. However, many of their erroneous theories can be explained by magnetoreception and magnetotropism. For a comprehensive review of the history and evidence of Davis & Rawls’ work, click here.
The researchers in the above study were able to carefully isolate the change in direction of the magnetic field and then assess any corresponding changes to the brain’s alpha wave patterns. Different subjects had different responses to the change in magnetic field. Some had 50% reductions in alpha wave activity after changes they were completely unaware of. And this is a subliminal area of the brain, one that the subject is not conscious of.

A very good article on the subject here on Gizmodo.
