Magnets on white board are too weak to stick!

[layman77]

I bought a whiteboard for our refrigerator with 4 attachable magnets on the back. They are rectangular magnets that I attached the magnets to the adhesives on the back, but when try to it attach it to the refrigerator, it can't even hold on to it! The white board just slides down the fridge to the floor. I guess I could get some stronger magnets to attach to the back instead.

 

But, is there anything I can do to strengthen the magnets already there? What if I attached 4 more rectangular magnets to the back to the magnets already there, so say the North Pole side of the magnet sticking to the fridge would be attached to the south pole of the magnets I attach to them, and then I could attach it to the fridge again?

Perhaps the part of the fridge your attaching it too isn't made out of magnetic material...
