Abstract: In recent years，electronic devices have been widely spread. Also，the fact that electromagnetic radiation　can do harm to our health has attracted more attention. Thus，the methods of measuring electromagnetic radiation are studied by many people. In this paper，we introduce the method of induction coil. By carrying out different experiments，we prove successfully the feasibility of the method. Finally，a three-dimensional magnetic field sensor is fabricated in terms of this method
