Two identical bar magnets with a length \( 10 \mathrm{~cm} \) and weight \( 50 \mathrm{~g} \)-weight are arranged freely with their like poles facing in an inverted vertical glass tube.
\( \mathrm{P} \)
The upper magnet hangs in the air above the lower one so that the distance between the nearest pole of the magnet is \( 3 \mathrm{~mm} \). Pole strength of the poles of each magnet will be
(1) \( 6.64 \mathrm{amp} \times \mathrm{m} \)
(2) \( 2 \mathrm{amp} \times \mathrm{m} \)
(3) \( 10.25 \mathrm{amp} \times \mathrm{m} \)
(4) None of these
