A vibration magnetometer placed in magnetic meridian has a small bar magnet. The magnet executes oscillations with a time period of $\displaystyle 2$ sec in earth's horizontal magnetic field of $\displaystyle 24$ microtesla. When a horizontal field of $\displaystyle 18$ microtesla is produced opposite to the earth's field by placing a current carrying wire, the new time period of magnet will be :
Official answer
(1)
$\displaystyle 4 s$
