800-lb. Magnet Treats Eye Injury
AN EYE magnet so powerful that it will pull a flatiron across a room has recently been installed in a Minneapolis, Minn., hospital to remove steel cinders from patients’ eyes. It is the largest eye magnet in the world and weighs over 800 pounds. One and one-half miles of copper wire are wound in the apparatus, which uses a 220-volt current.

    I don’t think that’s what this is about. It seems to me that the magnet is used to attract and remove little bits of steel that have gotten lodged in the eye.
