MFV: Application software for the visualization and characterization of the DC magnetic field distribution in circular coil systems

The characterization of the magnetic field distribution is essential in experiments and devices that use coil systems. We present an open-source application software, MFV (Magnetic Field Visualizer), for visualization produced by circular models, simulates, plots systems composed any number coils size placed symmetrically along same axis. Therefore, new design or well-known system, such as Helmholtz Maxwell coil, can be easily modeled simulated using MFV. A graph homogeneity also produced, showing work region where homogeneous according to a percentage given user. standardized input output file format are employed facilitate exchange archiving data. include some results obtained MFV, its applicability characterize different Furthermore, provided were validated comparing them with experimentally commercial coil. Obtaining maximum variability between experimental simulation flux density values axis symmetry 0.87%.
