A short magnet oscillates in a vibration magnetometer with a time period of 0.10 s where the horizontal component of earth's magnetic field is 24 mu T . An upward current of 18 A is established in the vertical wire placed 20 cm east of the magnet . Find the new time period.

A vibrations magnetometer consists of two indentical bar magnet placed one over the other that they are perpendicular and bisect each other. The time period of oscillation in a horizontal magnetic field is 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 :
