Swiss researcher developed magnet to remove foreign bodies

Magnets have led travelers and explorers safely home and have spared ship's captains from the ocean depths. Today, they play a major role in medicine in the analysis of ourinternal organs by the use of magnetic resonance imaging (MRI).

Ophthalmology also had its era of the use of magnets.
