A system and a method for calculating the magnetic field/current amount of the coil are provided to block the magnetic field of region from being influenced by the external magnetic field. An input-output part(101) comprises an input unit and a display device. If the magnetic field derivation is selected from the input unit, an operating module(103) enters into the magnetic field derivation mode and draws the magnetic field in coil. If the magnetic field derivation is not selected from the input unit, the operating module enters into the current amount derivation mode and draws the form of coil and the current amount. A storage(102) stores the equation for drawing the form of the magnetic field which is drawn in the operating module or the current amount. |
