Question
ciro 2) (from Lillian C. McDermontt, Peter S. Shaffer and the Tutorials in Introductory Physics, Prentice Hall,NJ, 1998,). Physics Consider four metal bars as in the diagram below. The bars are The ends of each bar are labeled A and B, and the mil of ach bar is ibe hd and the Physics bar is labeled A. A. Tn B. Bar 4 Bar 1 Bar 2 Bar 3 Assume that any objects that are magnets have their poles on the ends A and B. A student makes the following observations: (i) 1A attracts 2A (ii) 1A does not interact with 3m (ii) 1A repels 4B a) Classify the three objects as magnets, ferromagnets, or non-magnetic objects. Explain your reasoning. If you cannot classify some of the objects on the basis of the information given above, explain why not and describe experiments you could perform to help you classify the objects. b) How would 1A interact if it were brought near 4m? If it is possible to tell, what are the possibilities? Explain. bar ON Bar 2 Bar,Explanation / Answer
bar 1 is attracting as well as repelling so it is a magnet
bar 4 is repelled by bar 1 so its also a magnet as two magnets can only repel as the'll have same poles
bar 3 is non magnetic as it's not interacting with bar 1 which is a magnet
bar 2 may be a ferromagnet or a magnet as both attracts to the magnet
to verify we can see if bar 2 B pole is repelled by bar 1 A pole if it gets repelled then its a magnet and if not then its a ferromagnet
