Electromagnetic induction inside a field with a contraint

  1. May 3, 2012 #1
    1. A closed loop is held stationary in the magnetic field between the north and south poles of two permanent magnets held fixed. Can we hope to generate current in the loop by using very strong magnets?


    well, my doubt is: as magnetic field is a vector and since we have two pairs [one movable pair] we can alter the net field, right? [by holding in different positions] and thereby change the flux?
    anyway the answer is no and I believe I didn't get the concept right!

    It says both magnets are fixed. How do you jump to the conclusion that one of them is moveable?

    oh, sorry I meant to ask if one was movable can we make a change.

    Yes, if one or both were moveable then you could get current in the loop.
    But they're not, are they.
