| Abstract: | The specific features of inverse problems in magnetic field measurement are analyzed. It is pointed out that one of the difficulties in solving such problems encountered in practice is that there is not any analytic expression available, resulting in failure to problem solving and even confusion in conception. The field expression in space for a magnetic dipole is given with the matrix method and the corresponding inverse transformation formulas or the magnetic dipole moment formulas expressed with the space field are derived. Some inverse problems such as those in connection with the location of a magnetic body and the analytic system for a moving magnetic body are briefly discussed. |
