The answer should be CA) Any magnetic material can also be attracted by a strong magnet(incorrect)B) A magnetic material can also cause the compass needle to move as the needle is a magnet and the needle will move towards it (the needle is very light to cause movement but it will also move towards the object and hence incorrect )C) The question asked what CONFIRMS that an object is a magnet or not . If the 2 like poles are facing each other the object will rotate and then will attract to the other magnet . This will confirm that it is a magnet . If it had not been a magnet then it would directly be attracted to the magnet without rotating . Yes it is not necessary for it to rotate but the question says that what confirms , if the object rotates before being attracted to a magnet then it is a magnet and if it does not rotate before being attracted to magnet it can either be a magnet or not be a magnet (therefore it confirms that it is a magnet)D) If an object gets attracted to both poles of a magnet then it is a magnetic material but it confirms that it is not a magnet . Every magnet has 2 poles the north pole and the south pole , similar poles repel each other and different poles attract each other . If the object had been a magnet then it would have been attracted to only one of the pole and would have repelled the other . Only magnetic materials attract both the poles .
