| what are the magnetic materials | iron, steel, cobalt and nickel |
| what is a hard magnetic material | material that maintains its magnetism e.g. steel |
| what is a soft magnetic material | material that lose their magnetism easily e.g. iron |
| what is a magnet | - has a magnetic feild, - 2 opposite poles and will attract magnetic materials |
| what is a magnetic materails | - doesn't have a magnetic feild (can be induced around the magnetic materials), - attracted by a magnet |
| what is an induced material | when a non magnetic material develops magnetism, atoms in a magnetic material have a small magnetic force, pulled into line the material becomes a magnet |
| how can a material become magnetised weakly | material hold close to magnet |
| how can a material become magnetised strongly | stroke materal with pole of magnet |
| what is a magnetic feild line | the space around the magnet where magnetism can be found |
| how can an objects magnetism be induced | place magnetic metal inside a magnetic field inside a permanent magnet, and its magnetism will be induced. |
