The marked end of a compass needle always points directly to A magnet's south pole A magnet's north pole Earth's geographic South Pole Earth's geographic North Pole None 3. What kind of magnet is used in a magnetic compass ? permanent magnet temporary magnet none of the above electromagnet None 4. Which shape of magnet is used in electric bell? Horse-shoe shaped Cylindrical magnet Bar magnet Ball-ended magnet None 5. The N-pole of a compass points to the .............. pole of a permanent magnet north-east south north south-east None 6. Which effect of force is caused by the magnetic force between a magnet and a magnetic substance? Change of chemical nature. Change of shape. Change of physical state. Change of position. None 7. Which types of magnet have two poles close to each other? Horse-shoe magnet Bar magnet Cylindrical magnet Electromagnet None 8. _______ is the surest test of magnetism. No change None of the above Attraction Repulsion None 9. Which of the following will help demagnetizing a magnet ? Putting it in the water Cooling it Hammering the magnet Putting in contact with iron None 10. The presence of magnetic field at a point can be detected by galvanometer strong magnet ammeter a compass needle None 11. Which of the following is not attracted by a magnet? cobalt bronze steel nickel None 12. Complete the following statements with an appropriate word / term to be filled in the blank space(s).A compass needle is a ________ magnet : big small fieldless super None 13. What is the circular enclosure that the magnetic compass is placed in ? iron case stainless steel case aluminium case nickel case None 14. The device used by sailors and navigator to know the direction is called Wind vane Direction finder Magnetic compass Speedometer None 15. How will hammering a bar magnet affect Its magnetic strength? Is likely to decrease Will not change None of the above Is likely to increase None 16. Magnet was discovered by 17. Magnetic strength of the magnet is Concentrated at both the poles of the magnet Distributed uniformly throughout the magnet Concentrated at one of the poles of the magnet Concentrated in the centre of magnet None 18. How is a compass used to find directions? When suspended freely the compass needle aligns itself in the vertically up-down direction which gives us the perpendicular direction to the needle as north and south poles When suspended freely the compass needle aligns itself in the east-west direction which gives us the perpendicular direction to the needle as north and south poles When suspended freely the compass needle starts rotating in a particular plane and the axis of rotation perpendicular to the plane gives us north and south poles When suspended freely the compass needle aligns itself in the north-south direction which gives us the direction of the north and south poles None 19. The answer to which of the following options will distinguish between a magnetic material and a non-magnetic material? Is it a metal of a non metal? Can it be given an electric charge? Does it affect the direction in which a compass needle points? Is it a conductor or an insulator? None 20. A marine compass is used to determine H determine direction compare magnetic moments determine dip at a place None Time's up Please Share This Share this content Opens in a new window Opens in a new window Opens in a new window Opens in a new window Opens in a new window Opens in a new window Opens in a new window Opens in a new window Opens in a new window Opens in a new window Leave a Reply Cancel replyCommentEnter your name or username to commentEnter your email address to commentEnter your website URL (optional) Save my name, email, and website in this browser for the next time I comment.
