Give a reason to your answer Answer: The bulb will glow in circuit (D). Question 31. Since the South pole of the earth’s magnet is closer to the geographic North, the North pole of the suspended magnet will always rest in the geographic North, and the South pole of the freely suspended magnet will point towards geographic South. Do not touch the switch or any component with wet hands. The substances which do not allow electricity to flow through them are called insulators, e.g. Answer. Insulators — Glass, wood, paper, pure water, leather, plastic and ebonite. Answer. How will you test whether a given rod is a magnet or not?

State two ways by which the strength of magnetic field of an electromagnet can be increased. Draw a diagram to show a complete circuit to light the bulb. Answer. Describe in steps the procedure. A direct current source has the fixed positive and negative terminals, e.g. Give two examples of each. Question 1. Answer. 99 for a validity of 30 days. Contact us on below numbers, Select topic and apply filter to get exact results, Your question has been posted successfully. Answer: If we use a group of two or more cells, it is called a battery. The path along which an electric current flows is called a circuit. This is known as electric circuit. (h) Wool is a conductor of electricity. The poles are not exactly the ends of the magnet but thev are slightly inside. Both terminals of the bulb are joined with two metal wires to one terminal of the cell. Answer: Like poles repel and unlike poles attract. This is because copper is the best conductor of electricity as compared to aluminium. Electric fuse is a device which limits the current in an electric circuit. See that all the components of the circuit are properly connected. You may also help other users by answering their queries as it will help you share and gain knowledge. Hans Christian Oersted discovered that if an electric current is passed through a conductor, a magnetic field is developed around it. Draw a circuit diagram for a bulb connected to a cell with a switch. Now when there is no current there is no electromagnetism and the armature returns to the original position. Put yourself to the test and enjoy the fun trivia and electrical questions & answers, how much do you know about the interesting science topic of electricity? By increasing the current through the solenoid. For any content/service related issues please contact on this number. It has a soft iron piece called the core with an insulated copper wire wound on it. , music system etc Type of circuit contains two or more cells is called a battery Magnetism Magnetism electricity and magnetism class 7 questions and answers Class.
