Abstract :
A highly practical method for evaluating magnetic disturbance due to adjacent buildings for the design of a magnetic testing site with nearly zero magnetic field was proposed. A modeling technique for complicatedly distributed magnetic materials in buildings was verified by the measurement using an actually constructed building. Moreover, a convenient formula was conceived, in which a building is replaced simply into a brick magnetic body and the flux distribution due to its magnetization is calculated analytically. It was shown that the proposed formula is useful for investigating the effect of the positions of buildings for additional construction on the magnetic disturbance.
