Show answer
A permanent magnet produces its own magnetic field at all times, but a magnetic material only becomes magnetic when near a magnet.
Also accept: A permanent magnet always has a magnetic field, a magnetic material does not unless influenced by a magnet.; A permanent magnet is always magnetic, but a magnetic material needs to be near a magnet to show magnetism.
Common mistakes: Both are always magnetic; Magnetic materials can never be magnetic; Only permanent magnets can attract things
