You can check if the material is a magnet by the following methods:
1) Place the material in water such that it floats. If it is a magnet, it will come to rest at approximately the north-south direction.
2) If it doesn't float, suspend it with the help of a string such that it is freely movable. If it is a magnet, it will come to rest in north-south direction.
3) Take the supposed magnet and break it into two. If the pieces attract, it is a magnet.
4) Bring near the supposed magnet another magnetic material. If it attracts, then it is a magnet.
1st)
The advantage is that the compass always points north-south direction Whereas stars do not stay at fixed position Although in olden days and still the north star doesn't move but if its a cloudy night you won't be able to see any stars
