Magnets on wet surfaces?

Is it harder for magnets to stick if the surface of the refrigerator is wet?

Thanks!

    Refrigerator magnets are designed so that the magnetic force holding them to the fridge is MUCH greater than the weight of the magnet, so it would not be likely to fall down even if the surfaces of the fridge and the magnet were oiled.

    So the answer to your question is probably yes, but the difference is too small to matter, unlike you're using the fridge magnet to try to hold up some other object.

    no, the force of the magnet will squeeze out most of the water.

    but the water makes things slippery, so if you are trying to hold up something with the magnet, it may not hold.
