PSEB 6th Class Science Notes Chapter 13 Fun with Magnets
→ Magnetite is a natural magnet.
→ Some rocks have the property of attracting pieces of iron and these are called natural magnets.
→ Magnet has the property of attracting iron, cobalt, and nickel. Such substances are called magnetic substances.
→ Every magnet has two poles:
- North Pole
- South pole
→ A freely suspended magnet sets itself in a North-South direction.
→ Unlike (opposite) poles of two magnets attract each other whereas like poles repel each other.
→ Man-made magnets are called artificial magnets.
→ Magnets made from iron pieces are called artificial magnets.
→ Magnets are of different shapes such as Bar magnet, Horseshoe shaped (U-shaped) magnet, cylinderical magnet, or spherical magnet.
→ Compass is used to find direction.
→ When a magnet is brought near a compass, its needle gets deflected.
→ On heating a magnet, striking it with a hammer, or dropping it from a height it loses its property of magnetism.
→ If a magnet is not properly stored then it loses its property with time.
→ To store bar magnets with safety the opposite poles of two magnets are placed facing each other.
→ The magnet should be kept away from cassettes mobiles, TVs, CDs, and computers, etc.
→ Compass: Compass is a device that is needed to determine direction.
→ Magnet: Such substances which have the property of attracting iron are called magnets.
→ Magnetite: Magnetite is a natural magnet that was first discovered by a Shepherd named Magnus.
→ North pole: That end of a freely suspended magnet that points towards the geographical north direction is called its North pole.
→ South pole: That end of a freely suspended magnet that points towards the geographical south direction is called its South pole.
