some steel pins are dropped in a jar of liquid. the pins were then not attracted by a magnet.what could be the reasonand why?
A)jar is of non-magnetic material
B)Jar is made of magnetic material
C)the pins were not magnetic
The reason for it is that the water and the jar (if of glass) are non-magnetic material and act as shield against magnetic field of magnets. Thus shields steel (magnetic in nature) nails from getting attracted towards magnet.
