In the diagram above, if the south-poles of two magnets strokes steel bar, the polarities at T and V will respectively be
south and north
north and south
north and north
south and south
Correct answer is C
IN magnetisation by stroking, the last touched has a pole opposite to that of the magnet used. Therefore, the poles T and V are N and N respectively
