A bar magnet suspended in magnetic meridian executes oscillations with a time period of `2` sec in the earth's horizontal magnetic field of `24` microtesla. When a horizontal field of `18` microtesla is produced opposite to the earth's field by placing a current carrying wire, the new time period of magnet will be:

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

A vibration magnetometer placed in magnetic meridian has a small bar magnet. The magnet executes oscillations with a time period of 2s in the earth's horizontal magnetic field of 16 mu T . When a horizontal field of 10 mu T is produced opposite to the earth's field by placing a current carrying wire, the new time period of the magnet will be

At which place Earth's magnetic field becomes horizontal?
