Faraday's law of induction with ferromagnets?

  1. Feb 24, 2014 #1
    An electromagnet pulls a ferromagnet from a distance(r), now there is a change in flux. The total magnetic field in this case is increases or decreases?

    From my understanding the alignment of the domains should increase the magnetic field, but it is not noticeable...
    Now since there is Δ in B, there is -EMF induced, that is equal to the total B of the electromagnet + ferromagnet or just the ferromagnet's B? And that magnetic field is equal , less or greater than the electromagnet(assuming its a large piece of ferromagnet)?
