A quality-control worker checks a metal insert intended for a magnetic jewellery clasp. The worker holds a reference permanent magnet close to the insert and tests whether the insert attracts a steel paper clip. The worker then moves the reference magnet away and repeats the paper clip test.
Which result would show that the insert is an induced magnet and not a permanent magnet?
The insert is repelled by the reference magnet when the magnet is held close.
The insert still attracts the paper clip once the reference magnet is moved away.
The insert no longer attracts the paper clip once the reference magnet is moved away.
The insert is attracted towards the reference magnet when the magnet is held close.
