Abstract

Asked TAE his opinion about the size of magnet that could attract a 1/2 or 1/4 inch 200 lb plate of iron. [TAE replies: "Mott Answer this" "If the weight is to be moved like the bob in a pendulium a small magnet would {answer} but if the weight is to be lifted wholly against gravity it would require a magnet costing $175"]
