A square of side L meters lies in the xy-plane in a region, where the magnetic field is given by `=B_(0)(2hat"i"+3hat"j"+4hatk)T,`, where `B_(0)` is constant. The magnitude of flux passing through the square is

Text Solution

Verified by Experts

The correct Answer is:
c
Here, `vec(B)=B_(0)(2hati+3hatj+4hatk)T`
Aera of the squareb `'L^(2)hat(k)m^(2)`
`:.` Flux pssing through the squre,
`phi=vec(B)*vec(A)=B_(0)L^(2)(2hati+2hatj)*L^(2)hatk=4B_(0)Wb`
