WebThe neutron has a positive exterior and a positive core because the incoherent magnetic field is just the positive charge. The exterior field and interior field are constantly pairing away for a free neutron. In an atom this is fine because the core goes to the protons and its a feedback loop. Outside the atom it’s decay.
