If a fridge magnet sticks to fridges then does a bar magnet stick to bars?

Here is a video clip of the hair on the back of my hand moving in a mysterious way. Actually I have a Neodymium magnet concealed in my hand and its not hair but iron filings. I used to do this with the magnet in my mouth making a black moustache creep around my face. Problem is that I have a lot of fillings and if you get even one iron filing in between two filled teeth its very painful.
