    "abstract": "We derive the exchange currents of pseudoscalar, vector, and scalar mesons\nfrom Feynman diagrams, and use them to calculate the magnetic form factors of\nnucleon and $\\Delta(1232)$. The magnetic moments and electromagnetic radii are\nobtained by using those form factors and the parameters determined from the\nmasses of nucleon and $\\Delta(1232)$. We find the magnetic moments and\nelectromagnetic radii of nucleon and $\\Delta(1232)$ can be produced very well\nin the extended Goldstone-boson-exchange model (GBE) in which all of\npseudoscalar, vector and scalar meson nonet are included. The magnetic moments\nof $\\Delta(1232)$ are closer to experiment values and results from lattice\ncalculation than the results obtained by the model without other mesons except\nfor pion and sigma.",
