Experiments on Magnets

I am doing a science project on how magnets are effected by certain materials. I am going to place the objects inbetween the magnet and the metal object. How will cardboard, glass, or plastic effect the magnetic pull? They are used one at a time, not all at once.

Bob- I'm a little puzzled as to why you are asking us. As soon as you do the experiment, you'll know the answer!
