Consider a coil of wire carrying current I, forming a magnetic dipole placed in an infinite plane. If phi_(1)is the magnitude of magnatic flux through the inner region and phi_(0)is magnitude of magnetic flux through outer region then which of the following is correct ?

Answer»

`phi_(1) lt phi_(0)`
`phi_(1) GT phi_(0)`
`phi_(1) =-phi_(0)`
`phi_(1) = phi_(0)`

Solution :Flux emerging outward is positive and flux emerging inward is negative and value of both are equal.
`THEREFORE phi_(1) =-phi_(0)`
