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:

`1s`

`2s`

`3s`

`4s`

Text Solution

Verified by Experts
