(1) It is introduced the relation between modern biomagnetism and medical science and technology.

(2) Biomagnetism is new and interdisciplinary subject, it study magnetism of matter and the connection and affection between magnetic field and organisms.

(3) The soil magnetism data is the groundwork of biomagnetism application in agriculture.

(4) We elucidate the development of avian biomagnetism in relation to magnetic compass , navigating map and mechanism of magnetic induction in this paper.

(5) First, it is described the generality of the magnetic properties of matter and the magnetic field, and the principal contents of modern biomagnetism .

(6) Researchers say their study could provide fresh clues to explain biomagnetism – a phenomenon in which some birds, insects and marine life navigate using the magnetic field that encompasses the Earth.
