The answer is yes and no. Yes, if you’re using a strong magnet. Such types of magnet won’t fall off the fridge.  Additionally, magnetism won’t affect your fridge, including whoever touches the appliance. So, there’s no reason to feel bothered in that aspect.  Now, here’s where those tiny pieces of decoration most people have on their fridge can be dangerous.  For those that have little children at home, chances are the kids could attempt to swallow the decorative piece on your fridge in your absence. If they fall to the ground, someone might step on them and slip. Burning the decorative piece also has adverse health implications. Inhaling the smoke can lead to respiratory distress.
