153953 A vibration magnetometer consists of two identical bar magnets placed one over the other such that they are perpendicular and bisect each other. The time period of oscillation in a horizontal magnetic field $2^{5 / 4}$ s. One of the magnets is removed and if the other magnet oscillates in the same field, then the time period in second is

153954 With a standard rectangular bar magnet of length $(l)$, breadth $(\mathrm{b} ; \mathrm{b}\lt\ltl)$ and magnetic moment $M$, the time period of the magnet in a vibration magnetometer is $4 \mathrm{~s}$. If the magnet is cut normal to its length into four equal pieces, the time period (in second) with one of the piece is

153955 If two identical bar magnets, each of length $l$, pole strength $m$ and magnetic moment $M$ are placed perpendicular to each other with their unlike poles in contact, the magnetic moment of the combination is
