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

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 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:

At which place Earth's magnetic field becomes horizontal?

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.

Shown a short magnet executing small oscillations in vibration magnetometers in earth's magnetic field having horizontal component 24 muT . The period of oscillation is 0.1 s . When the key K is closed, an upward current of 18 A is established as shown. The new time period is
