Any object or material that produces a magnetic field
Magnetic field lines

How can field lines show you the strength of a magnetic field
The denser the field lines (the closer together they are), the stronger the magnetic field will be
How can you use a compass to visualise field lines
The needle of a compass always points along a field line towards the South Pole So can be used to find the field lines of a magnet.
How can you use iron fillings to visualise field lines
Place the magnetic under a piece of card
Sprinkle iron fillings over the piece of card
Tap the piece of card causing the iron fillings to accumulate along the field lines
