Needles 
and 
are made of a ferromagnetic, a paramagnetic and a diamagnetic substance respectively. A magnet when brought close to them will
A
attract all three of them
B
attract 
strongly, 
weakly and repel 
weakly
strongly, weakly and repel weakly
C
attract 
strongly but repel 
and 
weakly
strongly but repel and weakly
D
attract 
and 
strongly but repel 
and strongly but repel
Text Solution
Verified by ExpertsThe correct answer is:
B
A ferromagnetic substance is strongly attracted, a paramagnetic substance is weakly attracted and a diamagnetic substance is weakly repelled by a magnet. Thus, a magnet when brought close to needles 
, 
and 
will attract 
strongly, 
weakly and repel 
weakly.
