A nickel token is placed in the magnetic field of a permanent magnet and becomes magnetic. The token is then removed from the magnetic field. A short time later, the token can no longer lift a small iron pin.
Why?
The token remained an induced magnet, but induced magnetism causes repulsion after the source field is removed.
The token stayed magnetic, but a magnet can only exert a force on another permanent magnet.
The token was an induced magnet and lost most or all of its magnetism outside the field.
The token became a permanent magnet, but permanent magnets lose their own field when moved away from another magnet.
