Abstract
This paper discusses biomagnetic effects and their possible applications that are unfamiliar to cryogenic and superconducting engineers. Biomagnetism is exotic applied magnetics and a transdisciplinary research target. There are two types of research methodology, physical and epidemiological. They are quite different. Both methodologies should be harmonized. The author proposes how to work in this transdisciplinary field. Finally, suggestions of guidelines for studing exotic phenomena are presented.
