Many years ago, a tooling shop I worked in after school had an electric coil mounted on the wall. It was rectangular and measured something near 4" x 6" inside. to magnetize an object you would hold the object in the middle of the coil then push and hold the button for a count of 3 or so, then release the button and remove the object. To demagnetize an object you would hold the object in the middle of the coil then push and hold the button while drawing the object out of the coil. I am interested in building a magnetizer like that now. If anyone has seen plans for something like this I would appreciate any info you would care to share. Thanks, K.
