How to shield magnetic field of one end of a permanent magnetic bar ?

  1. Dec 3, 2007 #1
    I want magnetic force on one end of the magnetic bar only, but not on the other end. Will it work if I attach a big piece of iron on that end of magnetic bar which I do not want to have magnetic force? Imagine that big piece of iron will absorb all the magnetic flux from that end which i want it to be newtral ................

    You can redirect the field lines away from a region of interest, but that's about all you can do. You can not violate Gauss' Law. All the flux lines leaving one pole will have to enter the other pole.
