Problem
Traditional electromagnets create a magnetic field when current passes through them.
What I need is a magnet that loses its magnetic grip when current passes through.
Is there a particular name for these kind of magnets / systems?
Application
I want the magnet to hold a metal object (no energy should be consumed). With a push of a button (current applied) magnet should release the object.
