How do magnetic fields interact?

    I was wondering, how exactly do magnetic fields interact? Say if you have 2 permanent magnets, 1 perhaps of 0.3T and another of 0.5T and you let the N and S attract so they clamp together, would the resulting field of the combination have 0.5T on both ends (i.e. would the surplus 0.2T because of the "neutralized" 0.3T enhance the weaker pole? I realize it's an unconventional and perhaps incorrect way of thinking about magnets, but just curious:

    S[0.3T]N + S[0.5T]N = S[0.5T]N ?
