Which statement about magnetism and magnetic materials is correct?
A permanent magnet can be demagnetised by placing it inside a solenoid connected to a steady direct current (d.c.) supply and slowly withdrawing it.
Iron is a magnetically hard material, making it suitable for making permanent magnets.
Magnetic field lines always point from the South (S) pole to the North (N) pole outside a magnet.
An unmagnetised piece of iron is attracted to either pole of a bar magnet.
