Thank you all very much. I see from the wiki article and your response that air and wood have a similar affect. I need to calculate the pull strength so that I can buy the correct magnet (pull strength) to allow for the 1/4 inch gap. I will conduct more research. Thanks again!

Hi Folks: This is my first post, I hope that I observing the proper etiquette. If I have a magnet with a known pull strength is there a way for me to determine the affect of 1/4 inch plywood on the magnets pull strength when the plywood is placed between the magnet and the surface metal? Thank...

Thank you very much for accepting my application. I always loved physics, but never pursued it. My nephew is a physicist and he didn't know the answer to my question regarding magnetism/magnetic fields. I was hoping that I can ask it here.
