I just want to be up front with all of you, I am not a physics guy. I am trying to accomplish a goal. I need to focus a two inch electromagnet's energy into a quarter inch diameter area, four inches away from the magnet. Can this be done and how? Please explain in laymens terms, drawings would be nice. Thank you in advance for your time and thoughts. I must say, I am very impressed with the caliber of people on this site. Its good to know there are still thinkers out there.
