B Energy used to bring magnets together

  1. Aug 27, 2016 #1
    If you want 2 magnets to touch when the poles are the same 20160827_180549.jpg . Would it matter how you do it,moving them vertically 20160827_180519.jpg towards each other or horizontally? 20160827_180608.jpg

    Does it mater how you get them together and separate them?
    Would it use the same energy to join them horizontally as they would make repealing each other vertically?

    It does not matter. This is easy to see via conservation of energy.
