No but in cases, poles can be on the 2 edges lengthwise. But... they should be inter changed, that is, P should Steel bar and Q should be Bar magnet, isn't it?

The strength of a magnet is always stronger at its poles and not at the middle, so if we suppose Q as a bar magnet it will be wrong as it is written that in diagram 1 the strength of attraction is more but Qis attracting P from middle, so it is wrong
