Weakened Magnets?

  1. Jan 6, 2010 #1
    Hello all,

    First time poster and visitor here. I'm not sure if this is the right place to post this question, but I thought I might give it a try. The other day I came across something that puzzled me. I have one of those inexpensive wall cabinets in my bathroom from Target that comes with magnetic cabinet door latches. Granted, the unit is not engineered to perfection and the doors are not level, but somehow one of the doors opened on its own. That is to say, the door was in place and the magnet engaged but the door became unengaged and opened without any input. How can something like that happen? Can a magnet (in this case a cheap one I'm assuming) temporarily loose its magnetic properties? I've since tried to replay the scenario with various forms of physical shock (i.e., slamming doors and banging the walls) to no avail. Any explanation of this phenomenon would be greatly appreciated. Thank you!

    Sincerely,
    Randy Tashjian, MD
