VR Tour For Std. 6 Ch. 13: Fun with Magnets
What's Included in Virtual tour of this chapter
A magnet is an object which attracts magnetic materials. The material which gets attracted to a magnet is called magnetic material. For example iron, nickel, or cobalt. A magnet has two poles: the North Pole and the South Pole. Some materials get attracted to the magnet whereas some materials do not get attracted towards the magnet. The materials which are not attracted towards a magnet are called non-magnetic materials. We will also learn about the poles of a magnet and magnetic lines. There is always an attraction between opposite poles and repulsion between the same poles of magnet occurs. Magnets always settle in a north-south direction due to the magnetic property present in the earth. This property of magnet is used in the compass to find directions. Another interesting thing which we will learn about magnets will be that they can lose their magnetic property when they are heated.
Virtual tour 1: Types of magnet
During our childhood, we all have played with magnets or we still do have the magnetic badge on our refrigerator. There are four different kinds of Magnet: Bar Magnet, U Shaped magnet, Ring Magnet, and Horseshoe Magnet. The names of magnets are given based on their shapes. They all differ in shapes and sizes and also are made of different materials.
Virtual tour 2: Magnetic and non-magnetic materials
Materials can be classified into two groups on the basis of magnetism. One is magnetic and the other is a non-magnetic material. In this virtual tour, we will perform an experiment to understand which objects are magnetic and which are not.
Virtual tour 3: Poles of magnet
A magnet has the greatest amount of force i.e magnetism at its two ends. These ends are called Poles. Each magnet has a north and a south pole. The region around a magnet in which the magnetic force acts is called a Magnetic field.
Virtual tour 4: Attraction and repulsion between magnets
We will learn in this virtual tour about the attraction and repulsion of magnetic poles. When the two opposite poles of the magnet are there, then they will attract each other whereas if the same pole of two magnets is kept towards each other then they will repulse back. We will have more clarity in this concept by performing an experiment.
Virtual tour 5: Magnetic compass
Do you know the earth also has north and south poles like a bar magnet! Because of that a bar magnet always points in a north-south direction. The lines used to represent the magnetic field are known as magnetic lines of force. A Compass is an instrument used to find direction with the help of a magnetic needle. Because of the magnetism property present in the earth, the magnet device always points towards the north-south direction.
Virtual tour 6: Making of Magnet at home
Have you ever created your own magnet? There are several methods of making magnets. We are going to learn one of them in this virtual tour. By rubbing a magnet on an iron slab in a certain direction, it behaves like a magnet.
Virtual tour 7: A magnetism safety
Do you know magnets lose their properties in some situations? Magnetism can be destroyed by heating or hammering the magnet. Magnet loses its properties if it is heated. Magnets should be kept away from electronic devices like mobiles, laptops, televisions, music systems, etc.
