This is the neutron's magnetic field energy
Since we know the neutron's electric field energy as

  Then the neutron's  electromagnetic field energy becomes

  
  Assuming the neutron's  mass has an electromagnetic field origin, then
  
  
  
  
For the neutron, the  ratio of the magnetic energy to the electric field energy is
