CBSE Class 10 Physics Chapter 13: Magnetic Effects of Electric Current. We know that there is magnetic field around a bar magnet. How is it oriented? Can we draw the magnetic field lines around it? This is demonstrated in the video with the help of a magnetic compass and bar magnet.
CBSE Class 10 Physics Chapter 13: Magnetic Effects of Electric Current. We know that a current carrying conductor behaves like a magnet. What is the pattern of this magnetic field? This is explained with an activity in the video.
CBSE Class 10 Physics Chapter 13: Magnetic Effects of Electric Current. We have so far observed the pattern of the magnetic field lines produced around a current-carrying straight wire. Suppose this straight wire is bent in the form of a circular loop and a current is passed through it. How would the magnetic field lines look like? This is demonstrated with an activity in the video.
CBSE Class 10 Physics Chapter 13: Magnetic Effects of Electric Current. What is the force exerted on a current carrying wire in a magnetic field? What is Flemings left-hand rule? This is demonstrated by an activity.
CBSE Class 10 Physics Chapter 13: Magnetic Effects of Electric Current. What is an electric motor? How does it convert electrical energy to mechanical energy? This is explained with a demonstration in the video and the app.
CBSE Class 10 Physics Chapter 13: Magnetic Effects of Electric Current. What happens when a conductor is moved inside a magnetic field or magnetic field is changing around a fixed conductor? This is demonstrated with a coil and bar magnet in the video.
CBSE Class 10 Physics Chapter 13: Magnetic Effects of Electric Current. What is an electric generator? How are things set up in the electric generator? This is explained with a demonstration in the video and the app.
CBSE Class 10 Physics Chapter 14: Sources of Energy. What is a bio gas plant? How does it work? This is explained in this video with a working model of the plant.
CBSE Class 10 Physics Chapter 14: Sources of Energy. How can the solar energy be used to convert electrical energy? What are solar panels? This is explained with a demonstration of solar panel and solar cell.

CBSE Class 10 Physics Chapter 14: Sources of Energy. Hydropower plants convert the potential energy of falling water into electricity. This is a traditional source of energy. A demonstration of a working of a hydropower plant is explained in the video.
CBSE Class 10 Physics Chapter 16: Management of Natural Resources. Water harvesting is an age-old concept in India. Water harvesting techniques are highly locale specific and the benefits are also localised. A demonstrative explanation of the traditional water harvesting is given in the video.
CBSE Class 10 Physics Chapter 15: Our Environment. What is a food chain? Each step or level of the food chain forms a trophic level. Some of the food chains are explained in the video with demonstrations.
CBSE Class 10 Physics Chapter 13: Magnetic Effects of Electric Current. How does electromagnetic induction work when there are two coils with one connected to the power supply? This is demonstrated with an activity in the video.
CBSE Class 9: Atoms and Molecules Is there a change in mass when a chemical change (chemical reaction) takes place? Law of conservation of mass states that mass can neither be created nor destroyed in a chemical reaction. This is demonstrated with an activity.
CBSE Class 9: Structure of The Atom. In order to overcome the objections raised against Rutherford’s model of the atom, Neils Bohr proposed the model of an atom.
CBSE Class 9: Structure of The Atom. Thomson proposed the model of an atom be similar to that of a Christmas pudding. His model included the explanation of positive and negative charges.
CBSE Class 9: Structure of The Atom. Ernest Rutherford was interested in knowing how the electrons are arranged within an atom. He conducted experiments to explain the model of an atom.
CBSE Class 9: The Fundamental Unit of Life. The movement of water molecules through such a selectively permeable membrane is called Osmosis. This is demonstrated with an activity.
