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.
