Magnetism

Permanent magnet always produce a magnetic field, whereas induced magnets become magnetised when in another magnetic field.

Mini compasses or iron fillings can be put in a magnetic field in order to visualise it. We always draw the field lines going from the North pole to the South pole.

Iron, cobalt and nickel are magnetic (can become induced magnets) and so are attracted to permanent magnets. Other metals like aluminium and copper are not.

Opposite poles will attract each other; like poles will repel each other.
