A closed current carrying circular loop ...

A closed current carrying circular loop is placed on one face of a cubical box as shown in fig. The magnetic flux through area of the box contained by the loop is `phi_1` and the magnetic flux through remaining surface area of the box is `phi_2` . Which of the following option is correct

A

`phi_1 = phi_2`

B

`phi_1 gt phi_2`

C

`phi_1 =- phi_2`

D

`phi_1 lt phi_2`

Text Solution

Verified by Experts

The correct Answer is:
C
Magnetic flux through a closed surface is always zero.
So , `phi_1 + phi_2 = 0`
`implies phi_1 = - phi_2`
