    Do strong magnetic fields have any negative effects on the human body? Also, where can I find information regarding this subject?

    Not that I know of.

    This is interesting:
    A phosphene is an entoptic phenomenon characterized by the experience of light without light coming into the eye. Phosphenes can be created by intense, changing magnetic fields, such as with transcranial magnetic stimulation. These fields can be positioned on different parts of the head to stimulate cells in different parts of the visual system.
