Explanation 1) Concept: A permanent bar magnet in the form of a bar will have two ends as north and south poles. The attraction in opposite poles and the repulsion in similar poles is the property of magnets. We use this property to analyze the situation and conclude about the polarity of the bars. 2) Given: i) Four bar magnets of steel, out of which three are permanent magnets. ii) End b is the South Pole iii) Ends a and d, e and h, a and h attract each other. iv) Ends c and f repel each other. 3) Calculations: a) It is given that end b is a South Pole. Hence end a of the same bar must be the North Pole. An attraction is observed in end a and end e. Hence end e must be the South Pole. Then, other end, i.e., end f, of the same bar has to be the North Pole...
