Consider a short bar magnet forming a magnetic dipole enclosed by an imaginary co-axial cylindrical surface with circular base area. Magnet is at the middle of cylinder. If magnetic flux through one of the circular base is phi _(0) then the magnetic flux through the other circular base will be:

A

`phi_(0)`

B

`gt phi_(0)`

C

`-phi_(0)`

D

`lt phi_(0)`

Text Solution

Verified by Experts

The correct Answer is:
C
Net magnetic flux through cylinder is zero as mono-poles do not exist

`phi_("net") = phi_(I) + phi_(II) + phi_(III)`
`0 + phi_(0) + phi_(II) + 0 rArr phi_(II)= - phi_(0)`
